What does it mean when liver function test shows elevated GGT?
Elevated GGT in liver function tests generally refers to gamma-glutamyl transferase (GGT) levels above the normal range, which usually indicates damage to the liver or bile duct system.
Gamma-glutamyl transferase is a substance widely present in human tissues such as the liver, pancreas, and kidneys. The normal value is 0–40 U/L. Elevated levels may indicate inflammatory liver injury or inflammation and even obstruction of the biliary system, such as fatty liver, active hepatitis, cholecystitis, etc.
When elevated GGT is detected, further examinations such as abdominal ultrasound of the liver and gallbladder and hepatitis B panel testing are recommended to help identify the underlying cause, followed by targeted treatment under a doctor's guidance.
