What is considered extremely high GGT?

What is considered extremely high GGT?

In adults, GGT levels in the range of 0 to 30 IU/L are normal. Anything above 30 IU/L could be a sign that your liver isn’t working the way it should.

What happens if gamma glutamyl transferase is high?

A gamma-glutamyl transferase (GGT) blood test measures the activity of GGT in your blood. GGT may leak into your bloodstream if your liver or bile duct is damaged, so having high levels of GGT in your blood may indicate liver disease or damage to your liver’s bile ducts.

Can GGT be elevated for no reason?

Yes, GGT is very sensitive and can be increased when you don’t have symptoms. This elevation may be temporary, perhaps due to medications that you are taking or due to drinking alcohol within 24 hours of the test.

Is GGT elevated in diabetes?

GGT is a nonspecific marker that is known to rise in patients with type 2 diabetes. In epidemiological studies, it has a positive association with alcohol intake, cigarette smoking, coronary heart disease, BMI, systolic blood pressure, serum triglyceride, heart rate, uric acid, and hematocrit.

What does gamma glutamyl transferase do?

GGT functions in the body as a transport molecule, helping to move other molecules around the body. It plays a significant role in helping the liver metabolize drugs and other toxins. GGT is concentrated in the liver, but it’s also present in the gallbladder, spleen, pancreas, and kidneys.

How long does it take for GGT levels to go down?

Gamma–Glutamyltransferase Levels typically rise after heavy alcohol intake that has continued for several weeks (Allen et al. 1994). With 2–6 weeks of abstinence, levels generally decrease to within the normal reference range, with the half–life of GGT being 14–26 days.

What medications raise GGT levels?

GGT levels may be increased due to medications, such as carbamazepine, cimetidine, furosemide, heparin, isotretinoin, methotrexate, oral contraceptives, phenobarbital, phenytoin, and valproic acid.

How quickly can GGT levels change?


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

When should I worry about Alt?

While one elevated ALT test doesn’t necessarily mean that you have a health condition that needs treatment, several high ALT tests or a high ALT test in conjunction with symptoms of liver damage or disease are a reason for concern. Your doctor should work on finding the underlying cause and treatment options [48].

What is a GGT liver test?

A GGT test measures the level of gamma-glutamyl transpeptidase, also called GGT. GGT is an enzyme found throughout the body, but especially in the liver. A high blood level of GGT can be a sign of a problem in the liver or bile ducts (which carry bile from the liver to the intestines to help digest food).

What does it mean if gamma glutamyl transferase is low?

Usually, the higher the level of GGT, the greater the level of damage to the liver. If your results show you have low or normal levels of GGT, it means you probably don’t have liver disease. Your results may also be compared with the results of an ALP test. ALP tests help diagnose bone disorders.

What is gamma-glutamyl transferase (GGT)?

A gamma-glutamyl transferase (GGT) test measures the amount of GGT in the blood. GGT is an enzyme found throughout the body, but it is mostly found in the liver. When the liver is damaged, GGT may leak into the bloodstream.

Is serum gamma-glutamyl transferase a useful index of alcohol intake?

PMID: 11563810 DOI: 10.1080/20014091084227 Abstract Serum gamma-glutamyl transferase (GGT) has been widely used as an index of liver dysfunction and marker of alcohol intake.

Does gamma-glutamyl transpeptidase to platelet ratio predict liver fibrosis in hepatitis B virus (HBV)?

The gamma-glutamyl transpeptidase to platelet ratio (GPR) predicts significant liver fibrosis and cirrhosis in patients with chronic HBV infection in West Africa. Gut. 2015 doi: 10.1136/gutjnl-2015-309260. [PMC free article][PubMed] [CrossRef] [Google Scholar]

What is GGT in the liver?

GGT is concentrated in the liver, but it’s also present in the gallbladder, spleen, pancreas, and kidneys. GGT blood levels are usually high when the liver is damaged.
