Coagulation tests and coagulation assays are the gold standard for the diagnosis of<unk> . Prolonged activated partial thromboplastin time (aPTT), normal prothrombin time (PT), prolonged bleeding time (BT), and normal fibrinogen concentration are<unk>  of<unk> . Coagulation tests should be followed by measuring the clotting factors level by coagulation assays. Once the coagulation discrepancy has been established, individual clotting factor assay can be performed to determine the deficient/absent clotting factor. Bethesda assay can be performed in the case of acquired<unk>  to detect and quantify antibodies directed against factor VIII.
