The reagents within vW Select are finely tuned for optimal performance in Ristocetin CoFactor Activity Assay, presenting a three or four-point standard curve that achieves linearity. This innovative system replaces traditional lab-developed tests, ensuring regulatory compliance. Additionally, it reveals inflammatory responses, providing valuable insights into the patient's condition. The comprehensive package includes lot-specific reagent information and an assay value sheet, enhancing test performance, sensitivity, and repeatability while reducing assay and laboratory test variables.
Ristocetin CoFactor, as measured by the in-vitro activity of von Willebrand factor, triggers platelet agglutination. Reduced von Willebrand factor is associated with von Willebrand Disease, making quantitation of ristocetin cofactor activity crucial for diagnosis and evaluation of this coagulopathy. The assay is also instrumental in monitoring patient response to therapy. Results are determined by the ability of a test plasma and ristocetin to induce agglutination of a standardized platelet suspension, with outcomes interpreted using a lot-specific Standard Reference Curve.
The vW Select 50 Determination Complete Test Kit further simplifies the process, including lyophilized platelets, AggRecetin Reagent (Ristocetin), vW Normal Reference Plasma, vW Abnormal Control Plasma, vW Normal Control Plasma, Tris Buffered Saline, and AggRecetin (Ristocetin) Diluent. This comprehensive kit provides the necessary components for a thorough platelet function analysis, ensuring accuracy and reliability in clinical diagnostics.
