The presence of ethanol in the body can be measured through an alcohol blood test. Since alcohol is easily absorbed into the system, the amount in the blood can be measured a few minutes after it has been ingested.

Blood alcohol content, or BAC, is one of the most commonly used ways of determining not only if a person has been drinking alcohol, but also how much alcohol a person has consumed. Although a Breathalyzer test can estimate a person's BAC, to determine actual blood alcohol content, a blood sample must be used. blood sample for alcohol content is taken in the same way as any other blood sample, using a needle. The needle is placed into a vein and a collection tube is inserted into the back of the needle. The needle is withdrawn, and the collection tube is sent to a lab for testing.
