Alanine Aminotransferase (ALT) details

What Alanine Aminotransferase (ALT) shows

Alanine aminotransferase (ALT) is an enzyme found mainly inside liver cells; when those cells are damaged or inflamed, ALT leaks into the bloodstream, making it one of the two primary liver enzymes (along with AST) checked in a standard liver panel. ALT is generally considered more liver-specific than AST, since it's found in far smaller amounts in other tissues. Elevated ALT can have many causes, ranging from common ones like fatty liver disease, viral hepatitis, alcohol use, and certain medications, to less common causes like autoimmune or genetic liver conditions. Mild, temporary elevations are fairly common and not always a sign of serious disease, but persistently high or very elevated levels warrant further evaluation, usually alongside other liver markers like AST, ALP, and bilirubin.
