von Willebrand factor (vWf).activity actual/normal in Platelet poor plasma by Immunoassay --immediately after 1:1 addition of normal plasma

Active

Term Description

Decreased levels of von Willebrand factor (vWF) activity can lead to significant bleeding abnormalities. Decreased levels may be due to decreased production of von Willebrand factor or the presence of an inhibitor. Normal control plasma is added to patient plasma in equal amounts to evaluate the cause of the decreased vWF activity.
