How long does alcohol stay in your system to show a positive blood test?

Alcohol is eliminated from the body over time, and the rate of elimination varies from person to person. There are several factors that can affect how long alcohol stays in your system, including:

* Age

* Sex

* Weight

* Metabolism

* Amount of alcohol consumed

* Type of alcohol consumed

In general, it takes about 1 hour for the body to process one alcoholic drink. For example, if you have two drinks in one hour, it will take your body about 2 hours to eliminate the alcohol from your system. However, this is just a general guideline, and individual factors can affect how long it takes for alcohol to be eliminated from your system.

Blood tests can detect alcohol for up to 12 hours after your last drink. However, most blood tests for alcohol are performed within 2-4 hours of the last drink, as this is when alcohol levels are at their peak.

If you are concerned about how long alcohol will stay in your system, you can use a blood alcohol calculator to estimate your blood alcohol level based on your individual factors. You can also find more information about alcohol elimination on the National Institute on Alcohol Abuse and Alcoholism (NIAAA) website.
