    Hi Friends-

    Does anyone know what an Hepatic Function test is. I noticed today that my doctor gave me a script to have one done because of an elevated LFT (whatever that is). The doctor didn't telling me I was having this test done only other blood work so I am wondering what this is?

    It says on the order that it is being ordered because of an elevated LFT. Does that shed anymore light on this?

    ...Hepatic means pertaining to or affecting the liver.

    When someone has elevated Liver Function Test (LFT) the physician will order Hepatic Function Tests to get a better look at what is goin on. I would ask the physician why he ordered this. It could be he is taking a look if you are on some sort of long term durg therapy. Your best bet is to just ask at your next app't.

    The article below is from the University of Maryland Medical Center:


    A series of special blood tests can often determine whether or not the liver is functioning properly. These tests can also distinguish between acute and chronic liver disorders and between hepatitis and cholestasis.

    The most commonly performed blood tests include:

    Serum Bilirubin Test - Elevated levels of bilirubin often indicate an obstruction of bile flow or a defect in the processing of bile by the liver. Bilirubin is produced by the liver and is excreted in the bile.

    Serum Albumin Test - Below-normal levels of albumin, a protein made by the liver, are associated with many chronic liver disorders.

    Serum Alkaline Phosphatase Test - Elevated levels of alkaline phosphatase, an enzyme found in the bile, usually indicate an obstruction of bile flow, liver injury, or certain cancers.

    Serum Aminotransferases (transaminases) - This enzyme is released from damaged liver cells.

    Prothrombin Time (PTT) Test - This test measures the time it takes for blood to clot. Blood clotting requires vitamin K and a protein made by the liver. Liver cell damage and bile flow obstruction can both interfere with proper blood clotting.

    Alanine Transaminase (ALT) Test - This enzyme is released from damaged liver cells.

    Aspartate Transaminase (AST) Test - This enzyme is released from damaged liver, heart, muscle, or brain cells.

    Gamma-glutamyl Transpeptidase Test - This enzyme is produced by the liver, pancreas, and kidneys and released into the blood when these organs are injured.

    Lactic Dehydrogenase Test - This enzyme is released when organs such as the liver, heart, lung, or brain are injured.

    5-Nucleotidase Test - This enzyme is released by the liver when the liver is injured due to bile duct obstruction or impaired bile flow.

    Alpha-fetoprotein Test - This protein is produced by the fetal liver and testes, indicating hepatitis or cancer.

    Mitochondrial Antibodies Test - The presence of these antibodies can indicate primary biliary cirrhosis, chronic active hepatitis, and certain other autoimmune disorders.

    I hope this helps a little. Good luck to you.
