That said, GGT appears to be more sensitive than ALT and AST in detecting heavy alcohol use [79].

A person who has not eaten will hit their peak blood alcohol level between 30 minutes and two hours after consumption, depending on the amount of alcohol consumed.

The longer alcohol stays in the stomach, the longer it takes to be absorbed and the slower the rate of intoxication. Eating before drinking, and continuing to snack while you consume alcohol, will slow the absorption and reduce its impact, but prolong the detection period. The half-life of ethanol is about 4 to 5 hours, which means it takes that long to eliminate half of the alcohol ingested from the bloodstream. For most people, alcohol is absorbed into the system more rapidly than it is metabolized. The Cleveland Clinic’s Health Essentials site explains that alcohol can even be detected at the roots of your hair for 90 days after someone has stopped drinking.
