Additional Information
The ALT test is typically performed as part of a comprehensive metabolic panel (CMP) or liver function test (LFT). Normal ALT levels vary depending on age, sex, and health status, but generally range from 7-56 IU/L for adults. Elevated ALT levels can be caused by various factors, including liver disease, medication, or viral hepatitis.
The test is used to diagnose and monitor liver disease, such as liver cirrhosis, liver cancer, or autoimmune hepatitis. It is also used to monitor the effectiveness of treatment in patients with liver disease.
It is essential to consult with a healthcare professional to understand the test results and determine the best course of treatment.
