II. Labs: Markers of liver function and Protein synthesis

III. Labs: Markers of hepatocellular disease

  1. Alanine Aminotransferase (ALT)
    1. Most specific for hepatocyte injury
  2. Aspartate Aminotransferase (AST)
    1. Less specific than ALT (present outside liver)
  3. AST to ALT ratio
    1. Most liver conditions (e.g. NASH): Ratio <1
    2. Alcoholism: Ratio >2
    3. Wilson's Disease >4
  4. Lactate Dehydrogenase (LDH)
    1. Least specific for hepatocyte injury
    2. Dramatically increased in ischemic hepatitis
    3. Increased with alk phos in liver metastases

    2. Iron studies
    3. Ceruloplasmin (Wilson's Disease)
  2. Limited value: Anti-Smooth Muscle Ab

    2. Alpha-1 antitrypsin

Ontology: 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.
