A liver panel usually refers to several lab tests performed as a group. Depending on the physician or the laboratory, a liver panel usually includes tests for AST, ALT, bilirubin, and alkaline phosphatase.
The tests (called a liver panel) measure: 1  your level of liver enzymes (see next section) 2  your level of bilirubin (pronounced billy-roo-bin), which rises when the liver is not working well. 3  a protein called albumin (pronounced al-byoo-min), whose levels go down when the liver is damaged.
