Liver function tests are a group of blood tests that are used to assess the health of the liver. They can be used to diagnose a variety of liver conditions, including hepatitis, cirrhosis, and liver cancer. Liver function tests can also be used to monitor the effectiveness of treatment for liver disease.
Liver function tests are typically performed on a blood sample that is drawn from a vein in the arm. The blood is then sent to a laboratory for analysis. The results of the tests can be used to assess the levels of certain enzymes and bilirubin in the blood. These enzymes and bilirubin are produced by the liver, and their levels can be elevated in liver disease.
