AST and ALT are enzymes that are measured in a blood test to evaluate liver function. Here's a brief overview of each:
- AST (Aspartate Aminotransferase) : This enzyme is found in the liver, heart, muscles, and other tissues. An increase in AST levels may indicate liver damage, liver disease, or muscle damage
- ALT (Alanine Aminotransferase) : ALT is an enzyme found in the liver that helps convert proteins into energy for the liver cells. When the liver is damaged, ALT is released into the bloodstream and its levels increase. High levels of ALT in the blood may indicate liver damage or disease
These enzymes are part of a group of tests known as liver function tests, which check the levels of certain enzymes and proteins in the blood to assess liver health
. Abnormal levels of AST and ALT may indicate liver problems, and further evaluation may be needed to determine the underlying cause
