Where Gamma-Glutamyl Transferase (GGT) is reported
Also listed as: GGT
| Condition | Direction | Compared against | Associated symptoms | Source |
|---|---|---|---|---|
| Hepatitis C | ↑ elevated | healthy controls | — | Khadem Ansari et al. 2015 |
| NAFLD / MASH (Metabolic-Associated Steatohepatitis) | ↑ elevated | NAFLD with elevated inflammatory activity vs lower GGT levels | — | Liang et al. 2023 |
Frequently asked questions
In which conditions is Gamma-Glutamyl Transferase (GGT) altered?
In the OSMF atlas Gamma-Glutamyl Transferase (GGT) is reported in Hepatitis C, NAFLD / MASH (Metabolic-Associated Steatohepatitis). It is elevated in 2 across 2 entries.
Does Gamma-Glutamyl Transferase (GGT) point to one specific diagnosis?
No. Because Gamma-Glutamyl Transferase (GGT) changes in several conditions (Hepatitis C, NAFLD / MASH (Metabolic-Associated Steatohepatitis)), an abnormal result cannot identify which condition, if any, is present. It must be interpreted with symptoms, history and other tests.
Is there a standard clinical test for Gamma-Glutamyl Transferase (GGT)?
The atlas entries for Gamma-Glutamyl Transferase (GGT) do not carry a LOINC code, which usually means the marker was measured with research assays or study-specific methods rather than a routine clinical panel.
Is one abnormal Gamma-Glutamyl Transferase (GGT) result diagnostic?
No single biomarker result is diagnostic of any of these conditions. Findings reflect group averages from published cohorts with substantial overlap between patients and controls.
