Liver Blood Tests Topic Guide

Liver Blood Tests Liver Blood Tests: Liver blood tests are used to check the levels and function of liver enzymes in the blood called AST and ALT or aminotransferases in the blood. Symptoms of elevated or high liver enzymes in the blood include fever, abdominal pain, poor appetite, itching, and nausea. Normal levels of liver enzymes in blood are caused by liver diseases caused by drugs, for example, acetaminophen (Tylenol), pain medications, and statins. Less common causes of abnormal levels of ALT or AST levels in the blood are alcoholic and non-alcoholic liver diseases (NASH), hepatitis, and alcoholism.
