Does alcohol affect liver function test?
When people drink at harmful levels, liver cells are killed. The contents of the cells are released into the blood, increasing the GGT level measured in the blood test. If your result is higher than the normal range, it means that your liver is being harmed.
Can alcohol temporarily raise liver enzymes?
Alcohol is one of the factors most frequently associated with increased liver enzyme and the association between alcohol intake and alcohol-induced liver disease is well known.

Which liver enzymes are elevated with alcohol?
Liver disease is the most likely diagnosis if the AST level is more than twice that of ALT (9), a ratio some studies have found in more than 80 percent of alcoholic liver disease patients. An elevated level of the liver enzyme GGT is another gauge of heavy alcohol use and liver injury.
How serious is elevated liver enzymes?
