What is Liver function test?
A liver function test (LFT) is a blood test that helps a doctor determine whether the liver is functioning properly. The test measures the levels of liver enzymes in the blood as a way of helping diagnose liver problems. When the liver is injured, liver enzymes which normally are contained within the cells of the liver are spilled into the bloodstream. A liver function test may detect elevated levels of these liver enzymes if a patient has liver damage.
