Used for the detection and quantification of duck coagulation factor VIII (FVIII) activity in plasma samples, this ELISA kit is essential in research related to avian blood coagulation disorders. It enables accurate measurement of FVIII functional activity, supporting studies on hemophilia-like conditions in ducks and evaluation of anticoagulant therapies. The assay is also applied in veterinary diagnostics and breeding programs to identify carriers of coagulation deficiencies. Its high sensitivity and specificity make it suitable for monitoring disease progression and treatment efficacy in waterfowl health research.
