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).
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.
Only orderable as part of a profile. For more information see AVWPR / von Willebrand Disease Profile, Plasma.
