Factor VIII (FVIII) and von Willebrand Factor (vWF) are protein substances essential to the blood clotting process. In addition to being used as a replacement therapy for Hemophilia A, FVIII products that contain vWF are also used in the treatment of von Willebrand's disease, the most common bleeding disorder. Factor products are supplied in vial sizes of varying iu (international units) which may change with each new lot of product manufactured. |
