What does high GGT mean in a blood test?
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.
How long does it take for GGT levels to return to normal?
TRADITIONAL BIOMARKERS
| 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 can affect GGT levels?
An increased GGT level may be due to any of the following:
- Alcohol use.
- Diabetes.
- Flow of bile from the liver is blocked ( cholestasis )
- Heart failure.
- Swollen and inflamed liver ( hepatitis )
- Lack of blood flow to the liver.
- Liver tissue death.
- Liver cancer or tumor.
What does elevated GGT levels mean?
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 a high level of gamma GT?
For women younger than 45 years, a GGT level greater than 27 units per liter is considered high. For men and women older than 45, a GGT level greater than 38 units per liter is considered high. For children, the normal levels are about the same as for adults. For newborns, the normal range is five times as high as for an adult.
What does an elevated gamma GT mean?
Interpretation. An elevation of gamma-glutamyltransferase (GGT) activity is seen in any and all forms of liver disease, although the highest elevations are seen in intra- or posthepatic biliary obstruction. Elevated values can also indicate alcoholic cirrhosis or individuals who are heavy drinkers. The finding of increased GGT…
