Liver function tests

Liver function tests are blood tests used to help diagnose and monitor liver disease or damage. The tests measure the levels of certain enzymes and proteins in your blood.Some of these tests measure how well the liver is performing its normal functions of producing protein and clearing bilirubin, a blood waste product. Other liver function tests measure enzymes that liver cells release in response to damage or disease.Conditions other than liver disease or damage can lead to abnormal liver function test results. Test results can be normal in people who have liver disease or damage.
