Abstract
A simple method for the assay of factor VIII activity, based on the thromboplastin generation test of Biggs and Douglas, has been described.
Bovine serum is used as a source of factor V and serum factors, and plasma from a hemophiliac is not required. The concentration of factor VIII of the test plasma is compared to that of a standard normal human plasma. The results obtained with the method have been fairly reproducible.
