What does high gamma GT mean in a blood test?

The gamma-glutamyl transpeptidase (GGT) test measures the amount of the enzyme GGT in your blood. GGT blood levels are usually high when the liver is damaged. This test is often done with other tests that measure liver enzymes if there's a possibility of liver damage. Read more about other liver function tests.

How long does it take GGT levels to return to normal?

The combination of elevated MCV and GGT has a 95% sensitivity for alcohol abuse. GGT levels become elevated after 24 hours to 2 weeks of heavy alcohol consumption and return to normal within 2 to 6 weeks of abstinence, which allows them to detect binge drinking.

What does GGTP mean in a blood test?

A GGTP test is useful in only two instances: (1) It confers liver specificity to an elevated alkaline phosphatase level; (2) In aminotransferase level elevations with AST/ALT ratio greater than 2, elevation of GGTP further supports alcoholic liver disease. In addition, it can be used to monitor abstinence from alcohol.
