Understanding High GGT (Gamma-Glutamyl Transferase) Levels

GGT is an enzyme primarily found in the liver and bile ducts. High GGT levels (above 51 U/L) typically indicate liver disease, bile duct problems, or alcohol use.

What is Considered High?

A GGT level above 51 U/L is considered high. The degree of elevation can indicate the severity of liver or bile duct issues:

  • Mild elevation: 51-100 U/L
  • Moderate elevation: 100-200 U/L
  • Severe elevation: >200 U/L
