Von Willebrand Disease (VWD)
Part 4: VWF Multimer Analysis
The Role of von Willebrand Factor Multimer Analysis in Diagnosis
Type 2A VWD
July 2011
This next patient had a von Willebrand factor activity and ristocetin cofactor activity that was disproportionately reduced compared to the von Willebrand factor antigen. Multimer analysis demonstrated a decrease in the higher molecular weight multimers consistent with type 2A von Willebrand disease.
