What level of GGT is high?

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. Several types of liver disease can cause a rise in GGT, including: Viral hepatitis.

What should my GGT level be?

According to the Mayo Clinic, the normal range for GGT levels is 9–48 units per liter (U/L). Normal values can vary due to age and sex. The GGT test can diagnose liver damage, but it can’t determine the cause. If your GGT level is elevated, you’ll probably have to undergo more tests.

What does high GGT mean in a blood test?

An elevated GGT level suggests that a condition or disease is damaging the liver but does not indicate specifically the cause of the damage. In general, the higher the level, the greater the damage to the liver.

Can GGT levels go back to normal?

GGT levels may return to normal within weeks of reducing alcohol intake. This stands for Alanine Aminotransferase. This is another enzyme found in liver cells. Higher than normal levels indicate that the liver is being damaged.

Is GGT elevated in fatty liver?

Frequently elevated GGT levels can be evaluated as a significant factor for changes in fatty liver. Elevated GGT in non-alcohol drinkers is sometimes a surrogate marker for fatty liver [13, 14]. Our data suggest that frequently elevated GGT levels are probably a good predictor of fatty liver changes to come.

What does it mean if GGT 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 if only GGT is elevated?

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. High levels of GGT in the blood may be a sign of liver disease or damage to the bile ducts.

What does high GGT Alt mean?

High levels of liver enzymes GGT, ALT and AST are predictive of disease and all-cause mortality and can reflect liver injury, fatty liver and/or oxidative stress.

Should I be worried if my GGT 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.

What does GGT mean in a blood test?

In the GGT (gamma-glutamyl transferase) test, a healthcare professional measures the levels of GGT in a sample of blood. High levels of GGT in the blood can indicate damage to the liver or bile ducts.

What are the reference ranges for GGT levels?

The reference ranges for GGT levels vary between sources and laboratories. Normal levels are dependent on age and sex. Generally, they are higher in adult males than in adult females. The reference ranges based on 1,160 alcohol abstainers are organized below (one retrospective meta-analysis and one clinical study) [ 11, 12 ]:

What are the serum GGT levels for advanced fibrosis?

Using serum GGT levels the area under the ROC curve for the prediction of advanced fibrosis was 0.74 (95% CI: 0.54-0.94). The serum GGT cut-off value for the prediction of advanced fibrosis was 96.5 U/L; with 83% sensitivity and 69% specificity.

What causes high levels of the enzyme GGT?

High levels of the enzyme can be a sign of diseases that cause damage to the bile duct, such as gallstones, or to the liver. High GGT can also be a sign of liver damage due to excessive alcohol consumption.
