|Specimens:||1 ml Citrated plasma, frozen (cp)|
To avoid clotting please mix test tube carefully several times directly after collection of blood. Please centrifuge sample immediately, 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.
If additional coagulation tests are ordered (e.g. factor II - XIII), at least one extra tube of frozen citrated plasma is needed.

The von Willebrand's syndrome (vWS) is the most common cause of a congenital bleeding tendency (mild form up to 2 % of the population).
The von Willebrand's syndrome can also be drug-induced (frequently valproate-induced) or acquired, e.g. by autoantibodies and with lymphoproliferative diseases.The syndrome is usually not detected by means of common global tests such as Quick value, PTT or thrombin time. Often, however, the bleeding time is prolonged.
vWS can be classified into different types which require different therapeutic consequences. With positive basic diagnostics, special methods are available for differentiation (multimeric analysis, molecular genetic methods).
Classification of the hereditary vW syndrome:
Types 1 to 3 can be differentiated by the above-mentioned ratio formation:
Multimeric analysis, molecular genetic analyses
