GGT: units, conversion and tracking
Updated
Short answer
GGT is reported in U/L and µkat/L. 1 µkat/L = 60 U/L.

What is GGT?
Gamma-glutamyl transferase is an enzyme found in the liver and bile ducts.
BiomarkerHQ groups GGT under Liver. On lab reports it can also appear as ggtp, gamma gt, gamma glutamyl transferase, gamma glutamyltransferase and gamma glutamyl transpeptidase.
GGT units and conversion
BiomarkerHQ stores each GGT result in the unit printed on the report, and charts and compares results in U/L.
1 µkat/L = 60 U/L
1 U/L = 0.01667 µkat/L
| µkat/L | U/L |
|---|---|
| 0.2 µkat/L | 12 U/L |
| 0.4 µkat/L | 24 U/L |
| 0.6 µkat/L | 36 U/L |
| 0.8 µkat/L | 48 U/L |
| 1 µkat/L | 60 U/L |
| 1.5 µkat/L | 90 U/L |
| 2 µkat/L | 120 U/L |
| U/L | µkat/L |
|---|---|
| 10 U/L | 0.1667 µkat/L |
| 20 U/L | 0.3333 µkat/L |
| 30 U/L | 0.5 µkat/L |
| 40 U/L | 0.6667 µkat/L |
| 60 U/L | 1 µkat/L |
| 80 U/L | 1.333 µkat/L |
| 100 U/L | 1.667 µkat/L |
For another value, use the lab unit converter. It converts units only and does not interpret a result.
Tracking GGT over time
In BiomarkerHQ, each GGT result is saved with its collection date, its unit and the reference range printed on that report. The timeline charts the results across your draws against the range from each of your own reports, and any two draws can be compared side by side.
- Keep the unit printed on each report. Convert only to compare.
- Keep each report's own range with its result. See why ranges differ between labs.
- Compare the same lab and conditions where you can. See how to compare two blood tests.
Frequently asked questions
Which units do labs report GGT in?
GGT is reported in U/L and µkat/L. BiomarkerHQ stores each result in the unit printed on the report and uses U/L for charts and comparisons.
How do I convert GGT from µkat/L to U/L?
1 µkat/L = 60 U/L. For example, 0.8 µkat/L is 48 U/L.
How do I convert GGT from U/L to µkat/L?
1 U/L = 0.01667 µkat/L. For example, 40 U/L is 0.6667 µkat/L.
Does BiomarkerHQ interpret my GGT result?
No. It compares a result only with the reference range printed on your own lab report, as below, within or above, and does not say what the result means. Talk to a qualified clinician about your results.
