Tests & Procedures

Tests and Procedures: F

  • Factor I

    This test measures the amount of a protein called factor I, or fibrinogen, in your blood. It helps find out if you have a bleeding or clotting disorder.

  • Factor II

    This test measures how much of the protein prothrombin, or factor II, is in your blood. It can help diagnose bleeding and clotting disorders.

  • Factor IX (Antihemophilic Factor B)

    The factor IX test is part of a larger screening to find out which type of hemophilia you have.

  • Factor V

    This test looks for a deficiency in a protein called factor V. This protein is one of your body's "clotting factors." When you have too little factor V, you may have bleeding problems.

  • Factor VIII (Antihemophilic Factor A)

    This test helps find out whether you have hemophilia A or another clotting disorder.

  • Factor X

    This test checks for a deficiency in a protein in the blood known as Factor X. This protein helps with clotting.

  • Factor XI

    This test measures the amount of factor XI in your blood. Factor XI is a substance that plays an important role in blood clotting.

  • Factor XII

    This test measures the amount of a protein called coagulation factor XII in your blood. Factor XII is one of several clotting factors.

  • Fecal Fat

    This test measures the amount of fat in your stool. Having too much fat in your stool may mean that you have malabsorption.

  • Fecal Occult Blood Test

    A fecal occult blood test checks a stool sample for blood that can't be seen with the naked eye. Blood in the stool is a sign of bleeding in the digestive tract.
