Normal ALT Ranges
Typical reference ranges for Alanine Aminotransferase (ALT) in adults. Note that reference intervals can vary slightly depending on the specific laboratory and testing methods used.
| Demographic | Normal Range (IU/L) | Normal Range (µkat/L) |
|---|---|---|
| Adult Men | 10 – 40 IU/L | 0.17 – 0.67 µkat/L |
| Adult Women | 7 – 35 IU/L | 0.12 – 0.58 µkat/L |
| Children | 10 – 30 IU/L | 0.17 – 0.50 µkat/L |
ALT Conversion FAQ
Everything you need to know about ALT units and liver enzyme testing.
The conversion factor is exactly 60. To convert from microkatals per litre (µkat/L) to International Units per litre (IU/L), multiply the value by 60. To convert from IU/L to µkat/L, divide the value by 60.
Normal ALT ranges can vary slightly between laboratories, but generally, they are: Men: 10–40 IU/L (0.17–0.67 µkat/L), Women: 7–35 IU/L (0.12–0.58 µkat/L), and Children: 10–30 IU/L (0.17–0.50 µkat/L). Always refer to the reference range provided by your specific lab.
ALT (Alanine Aminotransferase) is an enzyme found primarily in the liver. An ALT blood test measures the level of this enzyme in the blood. Elevated levels can indicate liver damage or disease, as the enzyme leaks into the bloodstream when liver cells are injured.
IU/L (International Units per litre) is the traditional and most widely used unit globally. µkat/L (microkatals per litre) is the SI (International System of Units) standard, which is preferred in some countries, particularly in parts of Europe and Australia, for scientific consistency.
