How Long Does Alcohol Stay in Your Urine System – BAC Calculator

How long does alcohol stay in your urine and system is answered here. It is primarily based on the amount of alcohol consumed in what period of time. Other factors include body weight, gender and total time elapsed since drinking began and ended. In the human body, alcohol is metabolized at a rate between .012% – .015% of the blood alcohol concentration (BAC) per hour. A standard drink is considered one 12 oz. beer, one 5 oz. glass of wine or one 1.5 ounces of hard liquor. If someone was over the legal limit with a  BAC of .09%, it would take approximately 2 hours for an average person, to metabolize the alcohol in them.

  • The truth is trying to determine how long does alcohol stay in the urine system is a complicated mathematical formula.The formula is based on up to 5 to 10 variables.

The answer most people are looking for is “how long after I stopped drinking will I be able to pass a drug screen”. The answer is it depends on whether the test is a standard test or an EtG. More and more testing clinics run an EtG type test, but not all.

Rather then sharpening up your pencil and getting out your calculator, use our BAC Calculator below. If you have any questions or get a weird answer, please call us so we can help.

EtG Test Can Detect Drinking Alcohol 80 Hours After Its Out Of Your Body

An Ethyl Glucuronide (EtG) type of urine test can detect alcohol consumption up to 80 Hours after drinking stops, that’s right. An EtG type of test detects the presence of ethyl glucuronide in the urine. EtG is a direct metabolite the body uses to process alcohol. Its presence in urine may be used to detect alcohol consumption in the past 80 hours. With an EtG a positive urine tests are still possible 3 to 4 days even after low to moderate drinking.

Helping Get Alcohol Out of Your System Fast

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, juice & other fluids
  • Take a vitamin B supplement
  • Eat healthy food
  • Exercise

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.

How Long Does Alcohol Stay In Your Urine

How Long Does Alcohol Stay Your Urine & System – Liver

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.

The Science Behind Ethyl Glucuronide (EtG)

testing for how long alcohol stays in the urine systemSome labs now use a testing method known as “EtG” for discovering how long ago someone metabolized alcohol. “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 to 90  hours.

The “EtG” Urine Alcohol Test detects ethyl glucuronide in the urine, which confirms alcohol ingestion as long as 3-4 days prior, or about 80 to 90 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 recently. EtG has emerged as the test of choice for alcohol and due to the accuracy of this technology and is now routinely available. EtG’s presence in urine may be used to detect recent alcohol consumption, even after ethanol is no longer measurable using other methods. The presence of EtG in urine is a definitive indicator that alcohol was ingested recently.

The 4 Primary Factors in BAC

There are specific factors affecting BAC. Here are the 4 primary issues that will determine BAC.

Gender Type
The reason gender is a key factor is men  have a higher percentage (.58) of water weight than women (.49) by almost 10%. That means a woman’s BAC will be higher since BAC is based on converting water into the amount of blood in their body.

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, beer is figured as 4.5% – 5% alcohol, wine is figured using a 5 oz glass and hard liquor (shots & mixed drinks) are figured using 1.5 oz. at 80 proof.

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

Debunking The Myths

  • Speeding up metabolism of alcohol by drinking coffee or taking cold showers won’t work. Only time can reduce BAC
  • Even if you drank 24 hours ago, a breathalyzer test cold show you are legally drunk
  • Drinking the night before and then “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.

Breathalyzer

  • Breathalyzers detect alcohol in the blood within the past 24 hours of drinking

Saliva

  • An ethyl glucuronide (saliva) test can detect traces of alcohol in the body up to 12 days after drinking

Hair

  • 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

Calculate How Long Does Alcohol Stay in Your Urine System

This new BAC Calculator will detect how long does alcohol stay in your system. It is a fast, simple method to determine approximately what someone’s 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 to zero. The “BAC  Calculator” is easy to use.

 How The Human Body Metabolizes Alcohol

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; total number of grams of ethanol in 100 milliliters of blood. When about five percent of absorbed ethanol 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 stays in your system really depends on how much you drink over what period of time.

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.

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. Also, men have a higher amount of water in their bodies than women.

Genetics

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

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 Relate

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

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.

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).

Even a small amount of alcohol, such as a few beers can impair reaction time, coordination and good judgement. The legal BAC limit in all 50 states is 0.08.
