Von Willebrand disease (vWD) is a genetic disorder caused by the absence or abnormality of the von Willebrand factor (vWF). Because von Willebrand disease is a complex condition, its diagnosis requires a broad panel of tests to ensure accurate identification and classification. Multimer analysis is an integral part of the diagnostic process and provides essential information to physicians for optimal patient management.

The HYDRAGEL von Willebrand MULTIMERS kit is designed to detect abnormalities in the distribution of vWF multimers associated with bleeding disorders. The test evaluates the overall distribution of various sizes of von Willebrand factor multimers in human plasma using agarose gel electrophoresis and immunofixation, performed on the semi-automated HYDRASYS 2 instrument.
