What should I know about gamma gt wert blut?

Gamma-GT (gamma-glutamyl transferase) is a liver enzyme measured in blood, commonly used as a sensitive marker for liver and bile duct disorders. Elevated levels may indicate liver damage – often due to alcohol consumption, fatty liver disease (NAFLD), medications, or cholestasis. Obesity, diabetes, and certain drugs (e.g., antiepileptics) can also raise GGT. Normal reference ranges are typically below 40–60 U/L, but vary by laboratory. An isolated elevated GGT without other liver enzyme abnormalities is often non-specific and requires medical follow-up. Importantly, a normal GGT does not rule out liver disease. The provided context does not contain specific information about GGT; it focuses on genes like MTOR, PPARG, and TNF. Thus, this answer is based on general clinical knowledge. Evidence grade: practice. Safety note: At-home GGT tests should always be interpreted by a physician – do not self-diagnose or change therapy without professional advice.
