Alcohol Screen, Blood

The Alcohol Screen, Blood is a blood test that determines the level of alcohol in your blood. This test is recommended when there is a need to determine a person's blood alcohol (ethanol). This test may be ordered in a workplace setting for employees, for legal cases or accidents when driving or in a court of law, for medical testing to rule out alcohol poisoning, and to monitor individuals who are alcoholics. 

No special preparations are essential prior to this test. It is a relatively safe test that involves a needle prick for a blood sample. The result is denoted as a percentage or a number. The test is accurate within 24 hours period after the last alcohol intake. A positive result means that you have consumed alcohol recently, while a negative result means the absence of alcohol consumption within the detection window period.
