Monitor Your Liver Health - Alanine Aminotransferase (ALT) Test

Alanine aminotransferase (ALT), formerly known as GPT, is an intracellular enzyme found primarily in high concentrations in the cytoplasm of liver cells. When inflammation or damage occurs to liver cell membranes (hepatic necrosis), this enzyme is released into the bloodstream, leading to elevated levels. This makes it a relatively sensitive and specific indicator of liver disease compared to other enzymes.
