Lyophilized human citrated plasma immunodepleted for Factor VIII (FVIII). Residual FVIII activity <1%. CE-IVD. 1 × 1 mL.

Primary substrate for hemophilia A one-stage FVIII activity assay. Used in combination with CEPHEN™ APTT reagent — the absence of FVIII causes prolonged APTT inversely proportional to FVIII in the test sample. Essential for hemophilia A diagnosis, monitoring replacement therapy, recombinant FVIII product potency, and inhibitor assay substrate.

• Residual FVIII activity <1%
• Use with CEPHEN™ for FVIII one-stage intrinsic pathway assay
• For hemophilia A diagnosis and FVIII concentrate testing
