What is the purpose of testing Alanine Aminotransferase (ALT)?

The primary purpose of testing Alanine Aminotransferase (ALT) is to assess liver injury. ALT is an enzyme that is predominantly found in the liver, and when liver cells are damaged due to conditions such as hepatitis, fatty liver disease, or alcohol abuse, ALT is released into the bloodstream. Elevated levels of ALT can indicate that the liver is not functioning properly or is experiencing significant injury. Therefore, measuring ALT levels can provide valuable information regarding the health of the liver and help healthcare providers diagnose potential liver disorders. This makes it a crucial tool in evaluating liver function and identifying potential causes of liver damage.
