What does the GGT test indicate?

The GGT (Gamma-Glutamyl Transferase) test is primarily used to evaluate liver function and assess conditions related to liver disease and bile duct obstructions. Elevated levels of GGT can indicate a problem with the liver or bile ducts, such as hepatitis, cirrhosis, or the presence of bile duct blockages.

This is significant in clinical settings because GGT is particularly sensitive to liver dysfunction, making it a valuable marker for diagnosing liver diseases and monitoring the effectiveness of treatment. It can also help differentiate between different types of liver disorders.

While other tests may be used to assess kidney function, anemia, or electrolyte levels, the GGT test is specifically targeted at providing insight into liver health and related issues.
