Liver Function Tests Explained

Liver function tests (LFTs) are a panel of several blood tests used to assess and monitor potential abnormalities in the liver and hepatic system. Abnormal results may be due to one of two causes: damage to the liver itself, or a disruption in bile flow to or from the liver.
