Test ID AVWPI von Willebrand Disease Profile Technical Interpretation
Specimen Required
Only orderable as part of a profile. For more information see AVWPR / von Willebrand Disease Profile, Plasma.
Useful For
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
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.
