Gamma-glutamyl transferase (GGT) is primarily used to monitor what condition?

• A. Heart disease
• B. Alcohol levels
• C. Hemolytic anemia
• D. Muscle disease

Answer: (B)

Gamma-glutamyl transferase (GGT) is primarily used to monitor liver health, particularly in relation to alcohol consumption. Elevated levels of GGT can indicate liver damage or disease, and it is often a marker used to assess the impact of alcohol on the liver. GGT levels can become significantly elevated in individuals who consume excessive alcohol, making it a useful tool for monitoring alcohol use and potential liver complications.

While GGT can also be elevated in other conditions related to liver disease or cholestasis, its strong association with alcohol-related liver injury makes it a key enzyme in evaluating alcohol levels. This enzyme is not typically indicative of heart disease, hemolytic anemia, or muscle disease, which involve other specific biomarkers for accurate assessment and monitoring.
