Overview
About this test
The ALT (alanine transaminase) test measures a liver enzyme that's released into the bloodstream when liver cells are damaged or under stress. It's one of the most common tests used to check liver health, often alongside other liver function markers, and can be ordered as a general health check or to help investigate symptoms like fatigue, abdominal discomfort, or unexplained nausea.
What it checks
- Liver cell damage or inflammation
- Response to medications that affect the liver
