Factor VIII antibody

Hemostasis, or blood clotting, follows tissue injury and involves the deployment of essential plasma procoagulants (such as prothrombin, and Factors X, IX, V, and VIII) that trigger the blood coagulation cascade. This cascade leads to the formation of insoluble fibrin clots and the promotion of platelet aggregation. Defects in Factor VIII and the coagulation cascade result in hemophilia A, a common recessive X-linked coagulation disorder. This disease is characterized by uncontrolled bleeding into joints, muscles, and soft tissues.
