The enzyme that emonstrates highest serum activity in intrahepatic biliary obstruction and is also elevate in primary liver neoplasm is gamma-glutamyl transferase (GGT)
The amount of gamma-glutamyl transferase (GGT) in the blood is determined using a GGT test. While GGT is an enzyme present throughout the body, the liver is where it is most frequently found. The circulation may become contaminated with GGT if the liver is destroyed. High levels of GGT in the blood could indicate liver illness or bile duct injury.
Bile enters and exits the liver through tubes called bile ducts. The liver produces a fluid called bile. For digestion, it is essential. The precise cause of liver disease cannot be determined by a GGT test. As a result, it is typically performed concurrently with or following other liver function tests, most frequently an alkaline phosphatase (ALP) test.
