Choice of Anticoagulant for Primary Hemostasis Studies With PFA200® (Platelet Function Analyser)

Choice of Anticoagulant for Primary Hemostasis Studies With PFA200® (Platelet Function Analyser)

The PFA (platelet function analysis) test is prescribed for the exploration of primary hemostasis and the study of platelet-willebrand factor interaction. It is performed using citrated blood, with technical difficulties and frequent alarms that may be linked to the choice of anticoagulant (citrate). It is proposed to compare the results obtained with a conventional citrate tube and a BAPA tube, which is an anticoagulant used in clinical research and which blocks coagulation by another mechanism that would have less impact on blood platelets.
