Alanine aminotransferase blood test
The alanine aminotransferase (ALT) blood test is used to measure the levels of ALT in the bloodstream. ALT is an enzyme primarily found in the liver, and elevated levels of ALT in the blood can indicate liver damage or disease. Elevated ALT levels can be caused by various liver conditions, such as hepatitis, liver cirrhosis, or fatty liver disease. It is also commonly used to monitor liver function in individuals taking certain medications or to assess the effectiveness of treatment for liver diseases.
