Although some guidelines support this practice, we still have relatively little information about disease progression in patients with persistently normal liver enzyme levels. Researchers in India ...

To determine if elevated levels are directly related to liver damage, other tests need to be done. A comprehensive panel of tests known as a liver function test (LFT) will check for ALT and AST ...

The aspartate aminotransferase (AST) test is a blood test that looks for liver damage by checking the levels of aspartate aminotransferase (also known as aspartate transferase) in your blood.
