Tests used to check alcohol use can include blood alcohol levels, breathalyzer results, breath tests, and urine tests. While EtG and EtS urine tests provide a longer detection window for alcohol use, they have several drawbacks. The testing is not as widely available as a standard urine screening for ethanol and it costs more. EtG/EtS testing can’t tell you how much alcohol a person consumed, and it can’t differentiate between ethanol from alcoholic beverages and exposure to alcohol from other products. Alcohol can be detected in a urine sample within an hour of drinking, and it usually remains detectable for up to 12 hours.
In general, the liver can process one ounce of alcohol (or one standard drink) every hour. How long alcohol stays in your system depends on a number of external and internal factors, some of which are unique to every person. However, virtually all humans metabolize alcohol at a constant rate of 20 milligrams per deciliter (mg/dL) per hour, or 0.015 BAC every hour.
How Is Alcohol Metabolized in the Body?
However, various other factors can influence how long alcohol stays in your system. Read on to learn about how alcohol is metabolized and how long it stays in your system. It generally takes to liver about 1 hour to metabolize one standard drink for men. A blood test can generally detect alcohol for up to 6 hours after consumption. Passing an alcohol test in 48 hours can depend on a variety of different factors, including how heavily a person is drinking.
Similarly, people with anxiety who drink heavily may experience stressful emotions that can cause a change in the stomach’s enzymes, which affects how a person breaks down alcohol. Factors that determine how long alcohol stays in your body include liver size, body mass and the amount of alcohol consumed. A small amount of alcohol is removed from the body through sweat, urine and respiration.
How Does BAC Affect the Presence of Alcohol in Your System?
Our 110-bed facility is located near Colorado Springs, with breathtaking vistas and scenic views. We are one of several facilities in the Advanced Recovery Systems (ARS) network and are also a member of https://ecosoberhouse.com/article/how-long-does-alcohol-stay-in-your-system-blood-and-urine/ the National Association of Addiction Treatment Providers (NAATP). Commonly known as breathalyzers, breath alcohol tests (BATs) are administered by a technician and results are available immediately.
- Most methods of breath testing for alcohol actually focus on testing alcohol metabolites — chemicals that are made when alcohol is broken down in the body.
- When you consume alcohol, your body processes the substance at an hourly rate of one standard drink.

Once swallowed, alcohol enters the digestive system and travels to the stomach and small intestine. Approximately 20% of alcohol is absorbed through the stomach, and most of the remaining 80% is absorbed in the small intestine, then directly to the bloodstream. Once in the blood, alcohol is rapidly transported throughout the entire body, which is why alcohol impacts so many different bodily systems.
Questions About Treatment?
It would be very uncommon to find alcohol in your blood after 24 hours, even with heavy alcohol use. Alcohol is concentrated in breast milk within 30 to 60 minutes after having a standard drink and typically clears out in 2 to 3 hours. A blood test is most accurate when looking at direct biomarkers, yielding up to a 99% accuracy rate. Unlike indirect biomarkers, which are affected by alcohol consumption and other potential causes, direct biomarkers only arise from alcohol consumption.
Many aging adults also take medication that can affect liver function, slowing the process further. Just as family history plays a role in the development of an alcohol use disorder, how quickly the body processes and excretes alcohol also has a genetic link. A bottle of red wine commonly has about 7 and a half to 8 standard drinks per bottle.
Does Alcohol Show Up on a Drug Test?
There are many reasons why an alcohol drug test may be administered and many methods of detecting alcohol in the body. Depending on the type of alcohol drug test used, there are different lengths of time that alcohol in your system can be detected. Due to the short alcohol half-life, it usually doesn’t take too long for alcohol to leave your system unless someone continues drinking.
- How long alcohol stays in your system depends on your liver’s ability to process it.
- Alcohol can be detected in a urine sample within an hour of drinking, and it usually remains detectable for up to 12 hours.
- Alcohol is absorbed and eliminated from the body in many different ways.
- Instead of feeling happy or relaxed, they may begin to feel disoriented or irritated.
- If this happens too many times or too fast, damage to the brain and tissues of the body can develop.
After 48 hours, symptoms can continue to progress even further to delirium tremens (DTs) with more vivid hallucinations and delusions. There are many remedies marketed as “hangover cures,” but none have much evidence to support their use. Additionally, drinking can lead you to urinate more often and cause dehydration, so you can prevent any negative effects by taking in the water. Call your local emergency services if you suspect alcohol poisoning in a friend or loved one. The quicker you seek help, the more likely you are to minimize potentially fatal complications.
On average, it takes about one hour for the body to eliminate one standard drink. Individuals who have higher tolerances to alcohol, such as people with alcohol addiction, may eliminate alcohol more quickly. In urine, alcohol can be detected from 12 to 130 hours if a person has been drinking excessively. Phosphatidylethanol (PEth), a biomarker that reflects alcohol intake, can be detected up to 14 days in urine. Alcohol can be detected from 12 to 24 hours in the breath, as well as in saliva.
This is another metabolite that can detect the presence of alcohol in the body. Regardless of how fast your body absorbs alcohol, it eliminates it at the average rate of 0.016 BAC per hour. Nothing you do will speed up the elimination process, including drinking coffee, drinking water, taking a shower, or even vomiting. Roughly 20% of the ethanol in liquor is absorbed into the blood from the stomach and the rest from the small intestine. The longer alcohol stays in the stomach, the longer it takes to be absorbed and the slower the rate of intoxication.
