Term Description

This test measures von Willebrand factor (VWF) activity using a turbidimetric method with recombinant GPIb containing gain-of-function mutations. It quantifies VWF binding to GPIb without requiring ristocetin, offering improved precision and sensitivity compared to traditional VWF:RCo assay PMID: 25192242
