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


Marker Time to return to normal limits
Gamma–glutamyltransferase 2–6 weeks of abstinence
Aspartate aminotransferase 7 days, but considerable variability in declines with abstinence
Alanine aminotransferase Unknown
Macrocytic volume Unknown but half–life ∼ 40 days

What is a normal range for GGT?

The normal range for adults is 5 to 40 U/L. Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or may test different specimens. Talk to your provider about the meaning of your specific test results.

What foods raise GGT levels?

Not all factors that elevate GGT are well known, however some are. Certain diet patterns are associated with increased GGT, including consumption of red meat and alcohol, whereas consumption of non-fried or canned vegetables, grains, beans, tree nuts and coffee seem to be associated with lower levels of GGT[7].

Why do I have high GGT?

Possible Reasons for Elevated GGT. Elevated GGT levels can indicate numerous serious health conditions, especially cholestastic, or blocked, liver disease, hepatitis, liver scarring or a tumor. GGT is particularly sensitive to alcohol, and it is elevated in alcoholism and the use of medications and drugs, which have to be processed by your liver.

What does gamma glutamyltransferase measure?

gamma-glutamyltransferase ( GGT ) test. a blood test that measures GGT and is used to detect liver cell dysfunction. It accurately indicates cholestasis, biliary obstruction, cholangitis, or cholecystitis.

What is glutamyltransferase gamma GGT?

Gamma-glutamyl transferase (GGT) is an enzyme that is found in many organs throughout the body, with the highest concentrations found in the liver. GGT is elevated in the blood in most diseases that cause damage to the liver or bile ducts.
