Detection of deficiency or abnormality of von Willebrand factor (VWF) and related deficiency of factor VIII coagulant activity


Subtyping von Willebrand disease (VWD) as type 1 (most common), type 2 variants (less common), or type 3 (rare)


This test is not useful for detection of hemophilia carriers.


This test is not useful for differentiating type 2A versus 2B VWD or platelet-type VWD (pseudo-VWD).

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

If the factor VIII, von Willebrand factor (VWF) antigen, VWF activity and VWF activity:VWF antigen ratio are normal, a computer-generated interpretive comment indicating no evidence of von Willebrand disease will be provided.


If any test results in the profile are abnormal, all results will be reviewed by a coagulation consultant and a von Willebrand Disease Profile Interpretation (AVWPQ) will be provided.
