The alanine transaminase blood test (ALT blood test) measures the level of the enzyme alanine transaminase (ALT) in the blood. ALT is mainly found in the liver and helps break down proteins into energy. High levels of ALT can be a sign of liver damage or inflammation, often due to conditions such as hepatitis or fatty liver disease. This test is used to evaluate liver health, diagnose liver problems, and monitor the progress of treatments.
