Clinical Use

Using VWD testing portfolio in the diagnosis and monitoring of von Willebrand disease

Getting to a diagnosis of von Willebrand disease is a complex process and can require several medical visits and laboratory assessments. Usually, the patient’s clinical history, bleeding symptoms and the results of certain laboratory tests need to be evaluated. For the evaluation of von Willebrand disease, VWF activity assays can be combined with VWF antigen assays to detect and distinguish between quantitative and qualitative VWF deficiencies.¹ Make VWD testing available in-house, increase efficiency and improve patient outcomes with the Siemens Healthineers initial VWD testing portfolio!
