A urine test can usually pick up alcohol up to 24 hours after drinking, but a 2007 study showed that some tests can potentially detect alcohol for much longer. On the flip side, the same study showed that drinking a ton of water before a test can drastically dilute the amount of alcohol that shows up. The presence of alcohol can be detected through a urine test, breath test and even in your hair, says Healthline.com. Alcohol can be measured through your urine within 12 to 48 hours or even 80, depending on how advanced the testing is.
- Plus, in some states, drivers under the age of 21 have a different, much lower, legal BAC percentage threshold.
- As the alcohol hits your liver, the organ responsible for clearing toxins out, the liver responds by producing the enzyme alcohol dehydrogenase.
- Blood alcohol tests are more reliable than breathalyzers and are less likely to produce false positives.
- The U.S. government has approved several different devices for official use.
- Normally, your body quickly turns acetaldehyde into acetate, which is harmless.
So why do alcohol’s effects hit people so differently?
Alcohol can be detected from 12 to 24 hours in the breath, as well as in saliva. And when tested in the hair, especially at the root, alcohol can be detected up to 90 days after a person has stopped drinking. However, the higher percentage of body fat a person has the higher his or her blood alcohol concentration will be. This is because fat tissue contains less water than lean tissue, leading to less total body water and thus more alcohol in the blood. When it comes to ethanol urine tests, there’s going to be a small lag as the body filters the alcohol from the blood into the bladder. Urine alcohol levels generally peak 45 to 60 minutes after alcohol ingestion.
What blood test shows liver damage from alcohol?
While the body follows a standard process for absorbing and metabolizing alcohol, how fast it does this is different for everyone. And over time, your body and even parts of your body adjust, for instance, alcohol’s affect on the brain can be relatively short or life-long.

Symptoms of intoxication appear differently from person to person and leave the body at different rates.
Can you “sober up” faster with food or coffee?
It is estimated that between 90% and 98% of all alcohol that enters the body is metabolized and absorbed. The remaining alcohol is then expelled from the body through sweat, urine, vomit, and feces. The body follows a pretty straightforward process when digesting and metabolizing alcohol. Therefore, the amount of time that a drink will stay in someone’s system has more to do with how much a person drinks than any other factor. Alcohol blood tests are much less susceptible to false positives than breath tests, such as breathalyzers.
It is important to know that someone who drinks a lot or on an empty stomach may still have alcohol in their system the next day, making it illegal to drive a vehicle even then. For example, someone who has a BAC Of 0.08, which is when it becomes illegal to drive, will take around 5.5 hours to flush the alcohol out of their how long does alcohol stay in your system body. Studies have shown that both genetic and environmental factors can affect how the body processes and deals with alcohol. Some people of East Asian descent lack the enzymes necessary to break down alcohol. This can cause a reaction that includes facial flushing, nausea, dizziness, rapid heart rate, and headache.
Other major factors
A saliva sample can be taken to check for ethanol between 24 and 48 hours after taking the last drink. The breathalizer will be able to detect ethanol in the system after at least 15 minutes from the time of ingestion. This device will often be equipped with bands that estimate the amount present in the body. When two bands light up, that indicates BAC ranging between .05 and .10%. In the US, a level of 0.08 is considered, legally, as the threshold to indicate that a person is intoxicated. When BAC is above .40, a person is considered to be at risk of dying or falling into a coma.

Women also tend to have a higher percentage of body fat and a lower percentage of water, which influences intoxication and the length of time it takes to get alcohol out of their system. Alcohol use disorder also increases the risk of depression and suicide. It can also cause long-term health effects, such as cancer, liver disease, and brain damage.
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. A healthy liver will eliminate one normal-sized alcoholic beverage in about one hour. After a night of heavy drinking your BAC may still be over the legal driving limit the next morning. A breathalyzer is a device that measures a person’s alcohol concentration through a breath sample. These devices can detect alcohol for up to 24 hours, but this detection window varies between individuals. If you’re a heavy drinker, you may need to wean off alcohol to let your body adjust.
