Determining How Long Does Alcohol Stay in Your Urine & System

testing for how long alcohol stays in the urine systemDetermining how long alcohol stays in your urine system depends on several key factors. It will be primarily based on the amount and type of alcohol consumed recently, any food eaten during that period, age, weight, gender as well as several other variables of day-to-day living.

According to Medlineplus, a urinalysis is the physical, chemical, and microscopic examination of the content of someone’s urinary output. There are two methods of collecting urine; 24-hour urine collection and clean catch urine specimen.

A general urinalysis for alcohol might detect alcohol’s presence up to 48 hours after ingestion. Alcohol can last from 12 to 36 hours in your urine depending on a variety of factors including how long before the test you drank and how much you drank.

EtG Type Test Can Detect Alcohol for 80 – 90 Hours

Some labs now use a testing method known as “EtG” for discovering how long alcohol has stayed in your system. “EtG” is an abbreviation for Ethyl Glucuronide. Ethyl Glucuronide is a biomarker that determines whether the body has metabolized any alcohol recently. If a method known as “EtG”, is used to test for the presence of a related chemical, ethyl glucuronide, in the urine, the results can determine if alcohol has been ingested within approximately the past 80 hours.

The Science Of Ethyl Glucuronide (EtG) – How Long Does Alcohol Stay in Your Urine & System

The “EtG” Urine Alcohol Test detects ethyl glucuronide in the urine, which confirms alcohol ingestion as long as 3-4 days after intake, or about 80 hours after the liver metabolizes alcohol.The EtG test has become known as the “80 hour test” for detecting any amount of consumed ethyl alcohol. EtG has emerged as the test of choice for alcohol and due to the advances in technologies is now routinely available. Its presence in urine may be used to detect recent alcohol consumption, even after ethanol is no longer measurable using the older methods. The presence of EtG in urine is a definitive indicator that alcohol was ingested.

The Rate of Alcohol Metabolization in the Body – How Long Does Alcohol Stay in Your Urine & System

chart showing alcohol metabolizes determining alcohol metabolizationAlcohol is metabolized at the rate of approximately .012 – .015 of blood alcohol concentration (BAC) per hour. It is the equivalent to about one standard drink per hour regardless of your body size. Therefore, if you were legally impaired (BAC .08% or more) it would take roughly 51/2 hours for all the alcohol to be eliminated from the body.
The EtG detects the presence of ethyl glucuronide in urine. Ethyl Glucuronide (EtG) is a direct metabolite in alcohol. Its presence in urine may be used to detect recent alcohol consumption.

Positive urine tests are still possible several days after drinking moderately. Breathalyzers detect alcohol in the blood within 24 hours of drinking and an ethyl glucuronide (saliva) test can detect traces of alcohol in the body up to 12 days after drinking. Hair follicle testing for alcohol is the most precise and can detect alcohol in your system three months after ingesting alcohol. Detecting whether there is any ethanol in someone’s urine can be a very important determination.

Calculating How Long Does Alcohol Stays in Your System & Urine

The new “BACulator” is a fast, simple method to determine approximately what someone’s Blood Alcohol Concentration (BAC) might be at the end of a period of drinking. It will also immediately calculate the approximate amount of time it might take for that level of blood alcohol concentration to drop down to zero.

Fast, easy and convenient the “BACulator” takes less than a minute to use. It requires some specific information, of course. It is easy to read and reuse if necessary.

How To Use The BACulator – How Long Does Alcohol Stay in Your Urine & System

The “BACulator” is fast and easy to use, just do the following steps as indicated:

  1. Click on the computer icon to the left
  2. Fill in the information about Gender, Weight and Hours spent drinking
  3. Fill in the amount of the 3 types of alcoholic drinks consumed during the drinking period
  4. Click the “calculate” button

The results will instantly pop-up showing the approximate BAC level at the end of the drinking period and the approximate amount of time it might take for the level of BAC to drop down to 0.000.

The Primary Key Factors in Determining Blood Alcohol Concentration (BAC)

There are many factors which effect the blood alcohol concentration (BAC) in someone’s body who has been drinking.

BAC is the answer to this equation; grams of ethanol in 100 milliliters of blood

There are factors affecting BAC. Beside the 4 primary factors listed below, they also include age, how often someone drinks and how much food has been eaten recently.

Here are the 4 primary issues in determine someone’s BAC;

Gender Type
The reason gender is a key factor is men (.58) have a higher percentage of water weight than women (.49) by almost 10%.

Body Weight
How much someone weighs is a primary factor because blood alcohol content (BAC) is a function of “grams of ethanol in 100 milliliters of blood”. So, the more someone weighs the higher volume of blood there is in their body.

How Much Alcohol
The more alcohol someone drinks, the more alcohol your body needs to metabolize. Generally speaking, for most BAC tests, beers are figured as 4.5% alcohol. Wine is figured as 5 oz glass each and shots (mixed drinks) are 1.5 oz. at 80 proof.

The human body starts to metabolize alcohol as soon as the person starts to drink. In theory, if you drank at a rate of .015% BAC per hour your BAC would stay at zero ( everything else being relative).

How to Get Alcohol Out of Your System as Fast – How Long Does Alcohol Stay in Your Urine & System

Alcohol does show up on most drug tests. There is no “magic bullet” or over the counter products for cleansing our system of alcohol. These are some things to try that may accelerate the process:

  • Drink plenty of pure water
  • Take a vitamin B supplement
  • Exercise
  • Eat healthy food

Legally Speaking

From a legal standpoint, knowing whether or not someone has been drinking alcohol can determine someone’s ability to act in a responsible fashion. It is against the law to operate motor vehicle while under the influence over a certain percentage of alcohol. The amount of alcohol in a person’s body is known as their “blood alcohol concentration” (BAC).

The legal limit for BAC to operate a motor vehicle is .08 in all 50 states.

Gender Issues With Determining  How Long Alcohol Stays In Your System

Absorption rate factors involving gender indicate that a man weighing 140 pounds who consumes two drinks in one hour will have a lower blood alcohol level (BAC) than a 140-pound women who drinks the same amount of alcohol in the same amount of time.

This phenomenon can be explained by the fact that men possess higher levels of the enzyme hydrogenase. Once alcohol reaches the stomach, hydrogenase starts breaking down alcohol molecules, which facilitates metabolization by the body’s tissue and organs, specifically the liver. In addition, women present even higher blood alcohol levels compared to men just before menstruation since they also have lower percentages of water and higher percentages of alcohol-retaining fat cells.

Genetics Issues

Two enzymes control alcohol metabolism: aldehyde dehydrogenase (ALDH) and alcohol dehydrogenase (ADH). Geneticists have discovered that both ALDH and ADH are encoded by various genes in different forms. Which ALDH or ADH allele an individual carries will exert a strong influence on how long alcohol stays in their system as well as their risk for becoming an alcohol abuser.

Food Digestion Issues

When someone eats prior to or while they are drinking alcohol, stomach enzymes will fixate on digesting food instead of processing alcohol. This action delays infiltration of alcohol into the bloodstream, which means their BAC tends to peak between 60 minutes to six hours after consuming their last drink. Alternately, people who drink on an empty stomach will have a peak blood alcohol level within 30 minutes to two hours of taking their last drink. In addition, high-protein foods seem to delay processing of alcohol more than non-protein foods.

Individual Metabolism Related Issues

Some people have quicker baseline metabolism rates than others, a trait making then better equipped to process and eliminate alcohol. While metabolism is partly influenced by genetics, it is also partly controlled by lifestyle choices, stress levels, sleep and physical activity. Faster metabolisms correlate with people having healthy amounts of body fat and lean mass.

Medication Ingestion

Some prescription and non-prescription medications may inhibit processing of alcohol by interfering with enzymatic activity. Antidepressants, cold/flu medications and sedatives may cause faster absorption of alcohol in the small intestines, expedite higher BACs and lengthen time alcohol remains detectable in the body.

Illness & Disease Issues

Drinking alcohol while suffering an illness and/or disease that dehydrates the body often find alcohol stays in their system longer than when they are not ill. In addition to dehydration leading to reduced enzymatic activity, lack of sufficient water in the body interferes with the ability of the liver to degrade and eliminate alcohol. Taking medications while ill may further lengthen the amount of time alcohol remains detectable in body tissues, blood and urine.

Contrary to belief, drinking excessive amounts of water or other hydrating fluids does not expedite elimination of alcohol from the body. The liver is primarily responsible for metabolizing and eliminating alcohol from the body so that it is not detectable in the blood, urine or tissues.

Blood Alcohol Concentration (BAC)

When about five percent of absorbed alcohol reaches the kidneys, the body begins actively excreting alcohol through urination. Additionally, alcohol inhibits production of vasopressin, a hormone that helps conserve body fluids. Without vasopressin to prevent fluid loss, urination increases and the body usually begins excreting alcohol within 20 to 25 minutes of being consumed. However, determining how long alcohol remains detectable in your urine really depends on how much you drink.

Typically, the liver processes roughly one ounce of alcohol per hour. If you drink more than one ounce within one hour, your blood will contain excess alcohol that the liver is not able to metabolize. This unprocessed alcohol represents what law enforcement calls your “BAC”, or blood alcohol concentration.

While nearly 90 percent of alcohol consumed is metabolized by the liver, the remaining 10 percent is excreted through respiration, perspiration and urine. Drinking a beer or one mixed drink and then vomiting within a few minutes afterward may stop some alcohol from being absorbed into the blood but waiting longer than 15 or 20 minutes to throw up will do little to nothing to reduce your blood alcohol concentration.

If you drink more than one ounce within one hour, your blood will contain excess alcohol that the liver is not able to metabolize.

While nearly 90 percent of alcohol consumed is metabolized by the liver, the remaining 10 percent is excreted through respiration, perspiration and urine. Drinking a beer or one mixed drink and then vomiting within a few minutes afterward may stop some alcohol from being absorbed into the blood but waiting longer than 15 or 20 minutes to throw up will do little to nothing to reduce your blood alcohol concentration.

Without vasopressin to prevent fluid loss, urination increases and the body usually begins excreting alcohol within 20 to 25 minutes of being consumed. However, determining how long alcohol remains detectable in your urine really depends on how much you drink.

Once consumed, alcohol is rapidly absorbed by the stomach lining and small intestine. After entering the bloodstream, alcohol is then dissolved by the blood’s water molecules and transported expeditiously throughout the body. This “watered” down alcohol readily saturates soluble body tissues (except adipose tissue; alcohol does not dissolve in fat) and begins exerting its intoxicating effects.

The ingredient in alcohol that causes the well-known “drunk” affects is ethanol. Ethanol also impacts cardiovascular functioning by modifying LDL and HDL concentrations as well as influencing other chemical reactions:

  • Reducing the calcium ion flow within heart muscles inhibiting optimal contractions
  • Interfering with actin and myosin, two proteins influencing heart contractions
  • Decreasing the production of proteins needed for healthy heart contraction
  • Possibly enhancing harmful ethanol metabolites
  • Stimulating free radical activity

Abnormal heart rhythms and chemical interactions caused by alcohol may also contribute to how long alcohol stays in your system. Other factors determining the length of time alcohol stays in the body include:

  • Your weight and overall body size
  • Your metabolism rate
  • If undigested food is in your stomach
  • Type of alcoholic drink consumed
  • Being ill or dehydrated may elevate BAC, both can reduce liver efficiency
  • If you are under psychological or physical stress

Drinking mixed drinks containing carbonated beverages will increase internal stomach pressure and force alcohol into your bloodstream more quickly. Moreover, women have less dehydrogenase in their liver than men. Dehydrogenase is an enzyme that breaks down alcohol in the blood, so having less means most women will not experience alcohol’s affects as fast as most men do. Alternately, premenstrual hormone changes may facilitate intoxication due to water retention and the influence of rising progesterone levels.

More about Blood Alcohol Content AC

  • Speeding up metabolism of alcohol by drinking coffee or taking cold showers is not possible. Only time can reduce your BAC.
  • Even if you drank 24 hours ago, a breathalyzer test may still show that you are drunk or have abnormally high levels of alcohol in your bloodstream. Drinking the night before and “sleeping it off” doesn’t mean you’ll pass a BAC test.
  • Drinking water while drunk won’t make you drunker. In fact, drinking water can help dilute the amount of alcohol saturating body tissues and expedite excretion of alcohol through urine and perspiration.
  • Alcohol detox is an entirely different process than naturally eliminating alcohol from the body. Alcoholics needing detoxification should enter a medically supervised program due to health complications arising from the body’s strong dependence on alcohol.
  • Aside from suffering a “hangover”, occasional drinkers will not suffer the serious symptoms of abstaining from alcohol that alcoholics endure. The severity of alcohol detox symptoms also means that long-time alcohol abusers should never try to go “cold turkey” alone. Not only is this dangerous but sudden abstinence will not eliminate alcohol from the body any faster than a professional alcohol detox program can.

Reasons for Checking Urine for Alcohol

  • Someone is under a “zero tolerance” order by the justice system
  • Monitoring in alcohol rehab program, where abstinence is required
  • Early warning signs of a possible relapse in recovery
  • Comparison with blood alcohol, for determining legal impairment
  • Employee monitoring in the workplace

  1. I went to ReHab and they were worried about seizures??? I normally only drink on one or two days a week, no seizures. Now all of a sudden I need special monitoring? I got out of rehab and enjoyed a great drinking festival that day. I still only drink one or two days a week, and wasted about a month at Re-Hab…

    1. Alcohol detox can turn ugly. It is the only type of detox that can kill. My guess is they were only playing it by the “book”.

        1. If it is a “simple” test your body should have metabolized it by then. If it is an EtG, then you need 80-90 hours from your last drink before you might be safe.

    1. If they are doing a “EtG’ type of test it is possible to detect alcohol for 80-90 hours. In general, 1 beer could be metabolized out of the body in just a few hours.

      1. Hey I’m 145 lbs make. Fast metabolism, I drank about 5 beers Saturday night, and was completely abstinent for weeks until then. Been peeing alot and drinking water. Will I be okay for a etg about 48 hours later

        1. Hi

          According to most experts, it will take 80-90 hours to insure a person will pass an EtG, no matter how much water they consume.

        2. Yes you should be depending on your body. I drank 12 pack on a Tuesday night and took s test on Friday night and passed. So everyone’s body is different.

          1. I’m trying to get a comment from addict help for my question. I drank on Wednesday and Ua today Saturday, I weigh 125 female and they don’t do the EGt test. will I pass?

          2. Sorry for the delay, we would need to know exactly how much alcohol you drank and over what length of time to try and help you determine when the alcohol might be all out of your system. In general, if you didn’t drink too terribly much, you could be ok.

      2. I drank 3 bottles of 40oz old English and found out I have to do a urine test today, I am 5ft talland weigh 140lbp would I pass the test?

          1. When digging the ETG test can they tell how much alcohol was consumed? Also is there other household products or cooking with alcohol that will show a positive test

          2. generally not, EtG is a yes or no type of test. Mouthwash and hand sanitizer contain alcohol which can effect alcohol testing

  2. I drank 6 shots of Patron Tequila at 7 p.m.. Oct. 11th.
    Would this be out of my system for a urine test on Oct 17th???

    1. Depends on what kind of test it is. You should be good after 80-90 hrs for sure if you weigh less than 20″lbs. but, why chance it? I’m on papers, so I don’t take any chances, or to the slammer I go!

      1. It’s easy for you to say this. Many people are alcoholic & try thier best not to mess up. We all are hard headed & addicted!!!! So to hold on for a to long is very , very hard.

        1. thank you, and yes we forget sometimes how hard it is to not drink. Going it alone makes it even tougher. I often suggest to people they try going to AA meetings for some great and compassionate support.

        1. Hi – it is possible you will pass, if they do an EtG screen however you may not it can detect alcohol metabolization for 80 hours prior no matter how much water is drunk.

    1. it would probably be out of your system, maybe, but detectable on an EtG type test for 80-90 hours from the last drink

      1. If I drank one beer on Monday at around 2pm and I get tested on Wednesday around 12pm, will it show up on a drug test at a rehab facility?

        1. technically, the alcohol would be gone from your system by then. If they run an EtG type test, which can detect alcohol metabolization for the past 80-90 hours, you might not.

    1. ASAP and ASAP programs do test for alcohol and use the 80 hour test. Probation does not. Drink up if you are on regular probation.

      1. Is that true for jus regular probation I drank 6 talls of pbr and a few little ones Dec 23 drank lots of water had too pee on the Dec 26 thanks for your information I live in Cincinnati Ohio Hamilton county

        1. Hi
          No way for us to know county by county. Most counties run regular testing. It sounds like it would be close to the limit for EtG types of testing. If it is just a regular urine test, you should be ok.

  3. I drank a 40 oz last night and a few shots last one was at about 6… wouldnit be out of my system by 8pm today thats a little over 26 hours

    1. It could be your of your system in 25 hours, it impossible to say for sure. If they do an EtG type test, it can detect alcohol metabolization going back 80-90 hours

  4. Does the ETG hour count start from your last drink ingested or from when your BAC is at 0? I went on a bender. Last drink was Friday at 5pm and have a test Wednesday at 5pm. If by last drink I will have over 120 hours, if by BAC, I won’t.

  5. I work as fluid recovery associate. I am in consent exposure to gasoline, diesel and other ethanol based products daily. I was on SCRAM and it was turned off while I was at work. Does this exposure read as a positive during urine test?

    1. This is a bit out of our area of expertise. In theory, it is possible the exposure to ethanol could effect an alcohol test.

    1. if they don’t do an EtG type test you should be ok, if they do run an EtG, I am sorry to say you might come up positive.

    1. It should be out of your system by then, however, it would probably show up on an alcohol test using the eTg method of testing which can track back 80-90 hrs

  6. I had two beers on Saturday night and I have a regular drug screen (not etg) at 6pm. Will I pass? It will be over 60 hours after

  7. I had a tall can at 12 noon toda y have to test for probation tomarrow at like 11am will it be out of my system. Thats 23hrs. hrs

          1. I agree with you, and they are probably very sick of having to repeat themselves over and over………80 to 90 for etg test!!!!!

  8. Well…ETG… seems quite invasive and going to drastic extremes… which does not suprise me as our Country makes a great deal of profit from the sales of alchol….and our country makes a great deal of profit from those whom consume the legal substance… providing we obey the law and correctly preform our jobs i personally think .. if you are at work and your breath shows .02 so what? If you drive and you are .03 so what? I see no reason to dig and pry and try to say someone had a beer 80 hours ago

    1. I am on probation for two years for DWI. I have a breathalyzer on my car which will not allow me to start the engine if alcohol is detected. I believe it is not fair for me to have 0-TOLERANCE as my breathalyzer will prevent an occurrence.

      1. Hi
        Yes, that does seem a bit unfair. The thing is ANY alcohol can impair response time and coordination. Basically they are saying you can’t drink & drive.

    2. Do yourself the biggest favor in the world. Closely check your state’s laws or shell out $100 for a lawyer to do it. I was in Hawaii on vacation and rear-ended a car. I blew a .04, knowing I wasn’t drunk. HOWEVER — if there is something like a crash or someone gets hit or there’s property damage, your BAC below the legal limit can be deemed the reason or a contributor to the accident and it will be treated as a full-on DUI in the court and the administrative Dept. of Licensing. Also, if one relies on a CDL, it can be pulled if any alcohol is detected in relation to an accident. I learned the hard way, I really hope you don’t have to.

  9. I droped yesterday for dcs i droped exactly at 6:35 pm last use of achol was 52 hrs at that time it is an etg test I drank lots of flueds and pied a lot of times my weight is 137 pounds is their any hope I can be OK someone give me hope plz

  10. I only take small four shot at 11:30pm. I drink of 12 oz water at 1:45am then at 7:45am 12 oz. at 8am 3 bottle water of 12 hours. I will say at least 7 time went to bathroom. probation drug test at 2pm? will I make it pass ?

  11. Had 3 glasses of wine on weds last one was around 9pm might have etg on Saturday around 9am my metabolism in general is fast and I’m active…will I be okay

  12. I had a triple shot whiskey today. What can I do to make it extremely less likely to come up positive for a full ua on Friday night.

  13. I will be entering a probation program soon, and baring being forced to quit by the PO, I am a bartender. As such, I will occasionally take a small sample of a beer, wine or cocktail to learn a new flavor profile, or check that it tastes as it should. Since being arrested nearly two months ago I have not drank at all, but I still take these small samples while at work. The sample size is literally less than a thimble, and now I descretely spit it out immediately and rinse my mouth after. I’m trying to build a good habit in this bad situation, but when my probation finally begins, will this level of exposure put me at risk of failing an EtG?

    1. not likely but it is possible, so why take the chance? Just stop putting it in your mouth, then you’ll never have to worry about it.

  14. Had 1 airplane shooter of vodka at 1pm , 40% ach. Today 10.22. Have now a pop up text tomorrow at 4:30 pm, I work out side in Florida heat and drink probably a gallon of water. How should this test go?

    1. It depends on the sophistication of the test, you might pass, you might not, it’s impossible for us to say for sure, good luck

    1. EtG is the abbreviation for Ethyl Glucuronide, the enzyme the body produces when it metabolizes any alcohol. Non alcoholic beers still has a small amount of alcohol in it, some cold medicine does too. It sounds like there is a possibility your body may have has to metabolize a small amount of alcohol, but you still might be ok…

  15. I had 8 light beers on friday night thet21stlast drink was at midnight i haven’t had any alcohol in3 weeks my test is at 5pm on the 24 its almost 72 hours i been drinking lots of water im in pretty good shape u think i have a chance of passing. If i don’t here back ill give you all my resaults

          1. Hi All we can tell you for sure is that you have a fair chance of passing. We certainly hope you do.

  16. I drank about 3 to 4 oz of a bud light around 830pm and had a drug test the next day around 1130 am its etg test will i pass i drank very little

  17. I had to take a urine screen today for alcohol. I don’t know what type of testing system they use. I noticed a “F” on my paperwork so I asked what it was for. The guy that administered the screening said my urine had to be frozen. Is there any reason why? And what does that do to the urine? I had been drinking 2 days prior to this test

    1. Hi
      We are not sure, we think they may freeze it even though the test is completed in case there is any question about the results, after the fact.

  18. I drank a heavy liquor for that last 3 days my last shot of vodka was last night at 11pm. I’m going to have my ETG test in about 134 hours will I pass ? Tkx

  19. I have a urine test for alcohol on Monday between 6-7pm. If I drink past this time tonight will I still pass Monday? I weigh 150lbs and im 5’8″

  20. Hey I kissed my girlfriend who was drinking and have a drug test on Monday, it’s Sunday 4 am, will I pass? I tried spitting after we kissed so it wouldn’t get in my body

  21. I have been sober for 2 years and just finishing up probation for a DUI that happened 2 years ago. I made a “no bake” cookie recipe that used one teaspoon of almond extract. The extract bottle says it contains 36% alcohol. Will this show on on an eTG urine test?

    1. because they were “no-bake” a very small amount of alcohol was ingested. Since EtG’s are looking for the enzyme the body uses to metabolize alcohol, it is possible your test will come up dirty. Your explanation would be quite valid however.

    1. Hello

      According to most experts, it will take 80-90 hours from the time they stop drinking to insure a person will pass an EtG, no matter how much water they consume.

  22. I drank a lot of beer over a 2 weeks approx 16 beers. I have to take a new alocohl test I have 168 hours before test. My weight is 180with bad liver will I pass new test

    1. hi
      no way to know for 100% certain, too many variables, you are outside the 80-90 hour window so you should be ok, good luck

  23. I had 4 light beers and 4 heavy beers on sunday. My EtG test is Saturday at 1030. That will be about 130 hours later. Are you sure they can’t go more than 5 days? Some sites are saying 5 days.

  24. I am a heavy daily beer drinker. 10 or so a day. Last time I drank was Monday untill about 11pm. I have a UA on Saturday morning. Should this be enough time to pass?

  25. I’m also is a heavy dranker. Last drink was midnight, after 3 5.5%, 3 bud light and one strong mix drink. Might have to do the test on monday

      1. Female, 4.11 and 12 stone. Drank. We’d night, Friday 2 bottles and sat started at lunch time and finished last bottle 5 this morning, test midday friday

  26. 43 hrs will have passed before I have a urine test for alcohol consumption. I am 50yrs old and weigh approx 100 lbs. Ive been drinking tons of water sense my last glass of wine. Will I pass my test?

    1. Hi we can only say you may be at some risk, if it is an EtG type test. It can detect even a minimum amount of alcohol consumed in the past 80-90 hours. Otherwise the test s/b negative.

    2. Not knowing how much you drank, we can’t estimate the time to detox. If your test is an EtG type test, it can detect whether any amount of alcohol was metabolized in the passed 80-90 hours.

    3. I weigh 222lbs on Friday I drank about10 vodka drinks. I have to do a UA for my pain management Dr. On Monday @ 10:30. Will I pass?

      1. in order to accurately determine you BAC it would help to know whether you are male or female and also what time you started drinking on Friday.

  27. HI, I left a comment/question on here about drinking glass of wine then none for 43hrs….i weigh roughly 100lbs. My urine test is this afternoon…. please reply!!

    1. Hi we can only say you may be at some risk, if it is an EtG type test. It can detect even a minimum amount of alcohol consumed in the past 80-90 hours. Otherwise the test s/b negative.

    1. O’Doul’s is a non-alcoholic beverage, but still contains a small amount of alcohol. If your test is standard, non EtG type test, the results should be negative after 5-6 hours of consuming 4-5 non-alcoholic beers. EtG, however, can detect any alcohol that was metabolized in the past 80-90 hours (3.25 days).

  28. I am a 285 point female, 6″ foot, I have a drug test monday that can also test for alcohol , I’m going out with friends tonight to have about 6 beers , will that show up in my screening monday at 10 am. Today is friday

    1. If they do an “EtG” type of test, it can detect alcohol metabolization 80-90 hours (3.5 days) after stopping drinking. Otherwise, we estimate your BAC could be approximately .1072 after drinking 6 beers in about 4 hours. If that is true, then that amount could require approximately 10 hours for the average body to detox.

    2. We estimate it will technically be out of your system by Monday, if it is an EtG type of test, they can go back 80-90 hours

  29. With all due respect to all of you so concerned about passing ua’s; has it occured to you to just not drink???
    I would suggest that if you are facing any leagal consequence for drinking and you drink anyway – YOU MOST LIKELY HAVE A DRINKING MISUSE DISORDER and should go to AA!
    This is much better option than jail!

  30. I’m gonna drink 3/4 regular size bottle of white wine tonight (Friday) and probably have a ua Monday at 3pm. I have to take pain meds for chronic back pain and go to dr every 2 months where they do a ua. Do mds have that eg test in their office, or just standard ua testing? Think I’ll be ok? I’m 5’8″, about 165lbs.

    1. Drinking alcohol while taking opioids is dangerous. Not sure whether your doctor will run an EtG or not. If it is not, you will probably be ok.

    1. That depends, EtG tests are looking for whether someone has metabolized any alcohol within the past 3 – 4 days. So even though a person only consumed a small amount, like you did, it is a possibility that an EtG test could detect it. Otherwise, that small amount would disappear from the body quickly.

  31. Drank 6/16oz beers after 14 months sober. Have a EtG ua on december 4. 130lbs.male. Not very active but i do drink alot of water and sodas. Should i b ok? With ua test?

    1. Hi EtG can generally detect whether someone has metabolized any alcohol within the past 80-90 hours, about 3 1/2 days. So, in theory you should be ok. If, you drink ANY alcohol, even a small amount between the time you stopped and the test, the 3 1/2 day clock starts over…

  32. I drank a few sips of alcohol yesterday I am on probation in PA will I be good for a drug test in 2 days time and does pa use etg testing

    1. Every state is different, and no way for us to know about PA’s policy. In general, EtG can detect whether someone has metabolized any alcohol within the past 80-90 hours, about 3 1/2 days. If it is not EtG, then you should pass.

    1. Hello
      Your system will have completely metabolized 1 beer by Thursday. If they administer an EtG type of test, which looks for the enzyme used to metabolize (EtG) you still should be ok as it generally can only go back 80-90 hours.

  33. I stupidly drank around 18 light beers on nov. 26th, stopped around midnight, and weigh 195 lbs. I am to be pee test on the 30th at 1000-noon and I think its an etg but could be wrong. What are my odds? Thanks in advance for any response

    1. Also 1 more thing, can I claim I used mouthwash w/alcohol in it? Its not a test for legal reasons or anything but I really want to pass.

      1. in theory you could claim a positive result was caused by mouthwash, of course. A small amount could get into your blood stream and create a “false positive”. Be sure you know which brands contain alcohol as not all of them do.

    2. we would ned to know when you started drinking to accurately compute when your blood alcohol level could be down to zero…

  34. I’m a heavy drinker and I dranked a lot a week prior my last drink was Friday at 10pm my test is weds I’m 31 113 pounds? They will be testing for alachol.

    1. It is impossible for us to say whether anyone will pass an upcoming drug/alcohol test. We would need to know how many drinks you consumed in what amount of time or else we can’t compute hoe long the alcohol will stay in your system. Please let us know these details, thanks and good luck

    1. It is not possible for us to say for sure, based on the the facts you presented, you should be able to pass an EtG test 80-90 hours after the time someone stops drinking

  35. If I regularly drink about 4 whiskey and cokes every day for a month. Does the etg stay longer? I have my test next friday and I drank saturday. Would I still pass?

    1. We, of course, cannot guarantee the outcome of any test under any circumstances. If someone does not consume ANY alcohol for 5-6 days before being tested, they run a good chance of passing.

  36. If I failed a urine test for alcohol a week ago & I have a choice to have it retested. Will what determines if it reads the same & is there a time limit on ETG if it goes away after so long?

    1. Not sure exactly what you’re asking us here. The “rule of thumb” is an EtG can detect whether any alcohol has been metabolized in the past 80-90 hours. So someone would need to make sure they did not consume ANY alcohol 3 to 3 1/2 days before the time of the test.

  37. I took a squig not even a sip but something to touch my tongue, barely anything.. a etg won’t show that will it after a day or so?

    1. Hey Sam

      EtG tests don’t care how much you drank. It is looking for the enzyme the body uses to metabolize alcohol in the past 80-90 hours.

  38. Hi! I drank about 4 tall stiff drinks of rum that were about 1/2 alcohol and 1/2 soda for 5 days in a row. Every one of those nights my last drink was probably between 8pm-10pm. My last drink was about 10pm Saturday night. There’s a strong possibility I’ll have a urine screen at about 10am Tuesday morning. U think I’ll pass???

        1. HI It’s really hard to say, based on what you’ve mentioned, there is a pretty good chance you might pass. If it is an EtG test, however, it is possible you will not.

    1. EtG can detect any alcohol for about 80-90 hours. If it is not an EtG then we would need to know more about your gender and weight to estimate how long it might take to detox from than much alcohol.

    1. Hello

      There is no way for us to say for sure, if you don’t drink between Thursday at 500 PM and Monday at 500PM that’s approximately 96 hours, which is outside the 80-90 hour window of highest rate of detection.

  39. Male 158 lbs. Yesterday 8pm to 9 pm i drink 700 ml of beer with 6.9% of alcohol and our company conducted urine test today 3 pm in the afternoon. Will i pass?

    1. That is actually a lot more alcohol than it may sound like. Since the body, generally speaking, metabolizes alcohol at a rate of .012% – .015% per hour, there is a risk of coming up “positive” on a UA 16 hours after consuming it. We estimate your BAC at 8PM could be somewhere around .085, which is above the legal limit for driving a motor vehicle.

      1. Female…150 lbs. 3 glasses of wine on sunday between 10 pm and 12:15 am…etg at 4:30 Wednesday….i know the whole 80-90 hour detection thing, think lll test positive?

  40. Im155 lbs male started drinking on the 22nd at 8 pm half bottle of vodka 40% then same on 23rd and 24th and 3-4 shots on 25th stopped at 3pm will I pass a etg test on the 29th at 7pm? Been drinking a lot of water since I stoped

    1. we cannot say anything for sure, it looks like you stopped drinking ~100 hours before your scheduled EtG. Although it appears you consumed a fairly large amount of alcohol, you should have a pretty good chance of passing, but no guarantees.

  41. If I drink alcohol tomorrow at 6pm and it’s three glasses but have a test the next morning at 6pm will I pass my standard drug test is a charcoal tablet needed or no ?

      1. Hi, in order to compute the possibility of passing, I would need to know your gender, weight and the time period (# of hours) in which you consumed the alcohol

  42. Hello,

    I ate at a restaurant where they sauteed their onions with some vodka. I didnt drink and that was this Saturday. I may be tested this coming Thursday. Will this test positive with an EtG?

  43. Hey there I had a question my husband just got put on probation about a month ago and he was told not to drink anything and he hasn’t but he dranked right much before will it show up if they do a hair sample???

    1. good question, in theory it should not show up in a hair sample as it would be too close to the time he drank to be in his hair, unless they pulled a hair out.

  44. Hey this is Erica if I drank one wine cooler its4.2 will it stay in my system long I’m 120 weight and I pee in a cup for all drugs test

    1. We honestly do not know, the alcohol in 1 wine cooler would be metabolized in approximately 6-8 hours. However, if your test is an EtG type, that looks for Ethyl Glucuronide, the enzyme the body uses to metabolize alcohol. It can find Ethyl Glucuronide going back 80-90 hours, 3-4 days. Regular and EtG’s both would require using a cup.

    1. Hi Lee
      Since you are a heavy drinker, we can’t guarantee you will pass, even 24 hours after the EtG range of detection.

  45. I am 23 years old and weigh 170. If I had drank 10 beer and 10 shots on Wednesday and stopped at 2 in the morning on Thursday would I good for a test on Wednesday the next week would I be okay?

    1. Why would anyone drink that much alcohol knowing they are under any kind of testing situation? In theory, a human being is capable of metabolizing that massive amount of alcohol sufficiently in that period of time. Unfortunately there is no guarantee of passing, of course. Not knowing your gender it is not possible to compute your BAC accurately. Even if you drank all of it in say an 8 hour window, the BAC would be approximately somewhere around .40, 5 times the legal limit for driving, and a good candidate for alcohol poisoning and possible death…

      1. I’m a male and it was more like 5 shots and 7 beers which puts me at .19 using the calculator. With a total of 150 hrs after my last drank. I exaggerated for worst case scenario
