How is it used? The blood test for aspartate aminotransferase (AST) is usually used to detect liver damage. It is often ordered in conjunction with another liver enzyme, alanine aminotransferase (ALT), or as part of a liver panel or comprehensive metabolic panel (CMP) to screen for and/or help diagnose liver disorders.
The ALT blood test is a test for the substance known as Alanine Aminotransferase. Along with other substances such as Albumin, Aspartate Aminotransferase and Bilirubin, this substance is tested to check the health of the liver. Usually an ALT blood test is conducted as part of a series of tests that are conducted to determine the health of the liver. These tests are known as the liver panel tests.
