Alcohol Test Detection

How long does alcohol stay in your system?

It depends on the type of sample and drug test you give.

Urine Alcohol Tests – Generally urinalysis for alcohol can detect the presence of alcohol up to 48 hours after digestion. 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.

Hair Alcohol Tests – Using a sample of hair to test for alcohol allows experts to trace alcohol usage for up to 6 months.

Saliva Alcohol Tests – Saliva or oral, fluid-based alcohol tests can generally detect alcohol use for up to 12 hours after you stop drinking.

Blood Alcohol Tests –  It can take up to 2 hours for alcohol to show up in your blood. But once it’s there, a single ounce of pure alcohol is detectable for about 1.5 hours. If you reach a higher blood alcohol concentration (BAC), the alcohol will be detectable for longer, up to roughly 12 hours after you drink.

Factors That Influence Alcohol Detection Times

The level of alcohol detected in your system depends on the following factors, including your:

  • age
  • body mass
  • food intake / hydration
  • gender
  • liver function
  • metabolic rate
  • dosage / amount taken
  • frequency of administration

NOTE: Alcohol detection times in urine, blood, and saliva are an average and can vary greatly by individual. The information in this infographic should be used as a general guideline only.
