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

Converts units only and does not interpret a result. For other markers, use the full unit converter.
What is ALT?
Alanine aminotransferase is an enzyme found mainly in the liver.
BiomarkerHQ groups ALT under Liver. On lab reports it can also appear as alt sgpt, sgpt, alanine aminotransferase, alanine transaminase, alanine amino transferase and alat.
ALT units and conversion
BiomarkerHQ stores each ALT 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 ALT over time
In BiomarkerHQ, each ALT 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 ALT in?
ALT 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 ALT 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 ALT 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 ALT 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.
