The INNOVANCE VWF Ac1 assay supports improved diagnostic accuracy in von Willebrand testing

The INNOVANCE VWF Ac assay1 is a sensitive, reliable, and convenient test system for direct, WHO-standardized determination of von Willebrand factor (VWF) activity and is used as an aid in the diagnosis and monitoring of congenital or acquired VWF deficiencies in patients with bleeding disorders or at risk for VWF deficiency.

The INNOVANCE VWF Ac assay1 directly determines real activity of VWF. Due to the gain-of-function mutations, VWF binding to GPIb does not require ristocetin (VWF:GPIbM)2 and is therefore less susceptible to effects of certain polymorphism variants.

INNOVANCE VWF Ac assay1 shows excellent correlation with the ristocetin cofactor-based BC von Willebrand assay.
