vWF Multimers (cp) (Citrated plasma, frozen (cp))

Specimens: 1 ml Citrated plasma, frozen (cp)

Please always send a separate specimen for this test.

To avoid clotting please mix test tube carefully several times directly after collection of blood. Centrifugation process should be started after about 60 minutes. Please centrifuge sample at least for 15 minutes (1500 x g). Plasma / supernatant should be transferred by pipette to a collection tube without any buffer or other substances. Please label as citrated plasma. Freeze and send frozen.


Please note that this profile is a send-out test performed mainly for gel electrophoresis to assess von Willebrand multimer patterns. Von Willebrand activity and antigen values will be reported as well. vWF:Ac/vWF:Ag ratio will be noted only if pathologic.

Method: SDS gel electrophoresis
Set-up: on demand
Duration: 14 days

  • Common global tests such as Quick value, PTT or thrombin time are frequently normal.

  • Diagnostic assessment of haemophilia and thrombocytopathy

  • Therapy monitoring
