Liver Function Tests (C0023901)

Definition (NCI) The examination of the function of the liver using biochemical tests, radiologic procedures, or liver tissue samples.
Definition (NCI_NCI-GLOSS) A blood test to measure the blood levels of certain substances released by the liver. A high or low level of certain substances can be a sign of liver disease.
Definition (NCI) The quantitative measurement of liver enzymes in the blood, which is useful in assessing the functional state of a patient's liver. Liver function tests include the measurement of albumin, alanine transaminase, aspartate transaminase, alkaline phosphatase, bilirubin, and gamma glutamyl transferase.
