Liver function tests are blood tests used to diagnose symptoms and monitor liver disease or damage. These tests measure levels of specific enzymes and proteins in your blood. Some tests assess how well the liver performs functions like producing proteins and clearing bilirubin, a waste product.

Other tests measure enzymes released by liver cells in response to damage or disease. Irregular results don’t always indicate liver disease. Your healthcare provider will explain your results and their implications, helping determine if further testing or treatment is needed. Monitoring liver function is essential for managing liver health and preventing complications.
