Because of the need to relate haemophilic samples to the normal population, the unit of Factor VIII clotting activity (VIII:C) was first defined as the amount in 1 ml. of normal plasma. However, because of wide variation in the normal population, and poor stability of VIII:C in plasma, pooled normal plasma is unsuitable as a reference standard for ...

In Vivo Interactions of Autoantibodies to Factor VIII with the Factor VIII Complex
Thrombosis and Haemostasis, 1982SummaryTwo non-haemophilic elderly patients who had developed autoantibodies to factor VIII were studied over a period of 9 months to 5 years. Sequential measurements of antibody to factor VIII (anti-VIII: C), factor VIII coagulant activity (VIII: C), factor VIII coagulant antigen (VIII: CAg), factor VIII-related antigen (VIIIR: Ag), and factor VIII ...

Quantitative Evaluation of Factor VIII in Factor VIII Products.
Blood, 2004Abstract Several factor VIII products, recombinant and natural, have been used for hemophilia A treatment worldwide. Typically, two activity-based assays (factor Xase and aPTT) are used for the assessment of factor VIII concentration in these products.

To the Editor.— Rock et al 1 reported that in studies in 1982, the stated content of ampules of lyophilized antihemophilic factor (AHF, factor VIII) concentrates often exceeded the measured content, as assayed in the authors' laboratory. They stated that this discrepancy, with its implications of systematic undertreatment of classic hemophilia, has ...

Porcine factor VIII therapy in patients with factor VIII inhibitors
1995A review is presented of the use of porcine factor VIII (F.VIII) in patients with F.VIII inhibitors and acquired or congenital hemophilia. This review is drawn partly from the published literature and partly from an international survey of the use of porcine F.VIII in patients with congenital hemophilia conducted under the auspices of the ISTH F.VIII ...

Factor VIII and von Willebrand Factor
Thrombosis and Haemostasis, 1998IntroducationFactor VIII and von Willebrand factor are plasma glycoproteins whose deficiency or structural defects cause hemophilia A and von Willebrand disease, respectively (1). These diseases are the most common inherited bleeding disorders of man. Factor VIII and vWF are synthesized by different cell types and circulate in plasma as a tightly bound
