Diagnosis of von Willebrand disease (VWD) type 2N
Evaluation of patients diagnosed with mild-to-moderate hemophilia A with an autosomal inheritance pattern
Evaluation of hemophilia A patients with a shortened survival of infused factor VIII (FVIII) (not caused by a specific FVIII inhibitor)
Evaluation of female patients with low FVIII activity and no prior family history of hemophilia A
Evaluation of patients with Type 1 or Types 2A, 2B, or 2M VWD with FVIII activity discordantly-lower than the von Willebrand factor antigen level
This test is the most cost effective test for diagnosis of von Willebrand Factor (VWF): Factor VIII (FVIII) binding defects.
Genetic tests screening for variants that cause von Willebrand disease (VWD) type 2N are available. Limitations of genetic testing include expense and the potential for variants causing VWD 2N in regions not covered by the molecular assays.
