Liver Enzymes

Meaning

Liver enzymes are specific proteins, primarily alanine aminotransferase (ALT) and aspartate aminotransferase (AST), found in high concentrations within hepatocytes, the primary functional cells of the liver. The measurement of these enzymes in the peripheral bloodstream serves as a crucial clinical diagnostic marker for hepatocellular injury or inflammation. Elevated serum levels typically indicate that liver cells have been damaged, releasing their intracellular contents into circulation, which warrants immediate investigation into potential hepatic stress or dysfunction. Monitoring these enzymes is vital during hormonal or pharmacological therapies.
