von Willebrand Disease Panel without Collagen Binding Assay (CBA)
Also known as: vWF, VWD
Use
This panel is intended for the diagnostic evaluation of suspected von Willebrand disease (VWD). The omission of the collagen binding assay (CBA) suggests reliance on other von Willebrand Factor (VWF) assays—such as VWF antigen and activity measures—to assess quantitative and qualitative VWF abnormalities, helping discriminate between types of VWD.
