What is it indicated for?
IL Test™ von Willebrand Factor is an in vitro diagnostic automated latex enhanced immunoassay for the quantitative determination of von Willebrand Factor Antigen (vWF:Ag) in human citrated plasma on IL Coagulation Systems. When a plasma containing vWF:Ag is mixed with the Latex Reagent and the Reaction Buffer, the coated latex particles agglutinate. The degree of agglutination is directly proportional to the concentration of vWF:Ag in the sample and is determined by measuring the decrease of transmitted light caused by the aggregates (turbidimetric immunoassay).
