Diagnostic Considerations

Other problems to be considered in the differential diagnosis of hemophilia B include the following:

  • Hemophilia A and von Willebrand disease

  • Other inherited coagulation disorders - Multiple vitamin K–dependent factor deficiencies and FXI deficiency

  • Acquired antibodies against FIX in persons with known hemophilia (for more information, see Medication)

  • Acquired antibodies against FIX in patients without hemophilia

  • Common coagulation disorders secondary to liver disease, warfarin sodium or heparin overdose, disseminated intravascular coagulation, dysproteinemias causing coagulopathies, and vitamin K deficiency
