Factor VIII (FVIII, F8) Antigen ELISA Kit

VisuLize FVIII Antigen ELISA Kit

The VisuLize FVIII Antigen Kit is intended to quantitatively measure factor VIII (F8) in human plasma and factor concentrates. The biological importance of factor VIII (F8) is demonstrated in Hemophilia A and those patients suspected of thrombophilia. The laboratory diagnosis of factor VIII (F8) deficiency in Hemophilia A typically involves quantitative determination of factor VIII’s functional activity. The use of this kit in conjunction with functional assays in the area of gene therapy, assessment of factor VIII (F8) concentrates, as well as distinguishing those patients with cross-reactive material will prove useful in the area of Hemophilia A. Additionally as documented in numerous studies, elevated levels of factor VIII (F8) is being recognized as a common risk of venous thrombosis┬╣, an area where Affinity’s VisuLize FVIII (F8) Antigen Kit has utility.

The VisuLize FVIII (F8) Antigen Kit is FDA cleared, Health Canada approved, CE marked for in vitro diagnostic use.
