Lyophilized human plasma containing high-titer inhibitory antibodies against Factor VIII (FVIII). Severe inhibitor level. For positive control use in Factor VIII inhibitor (Bethesda) assay research.

Contains high-titer anti-FVIII antibodies for validating Bethesda assay performance at severe inhibitor concentrations (>5 Bethesda units). Enables verification of assay accuracy across the high-titer range relevant to hemophilia A inhibitor research.

• High-titer / severe FVIII inhibitor — validates high-range detection accuracy
• For Bethesda assay positive control in hemophilia A inhibitor research
• Lyophilized human plasma
