I need your help. I have only a brief acquaintance with CenterChem’s Pefakit prothrombinase-induced clotting test (PiCT). Samama MM, Guinet C, Laboratory assessment of new anticoagulants. Clin Chem Lab Med 2011;49:761–72 supports the PiCT for monitoring fondaparinux, dabigatran, and rivaroxaban (with minor modifications). The PiCT has been available for at least ten years for monitoring standard unfractionated heparin and low molecular weight heparin. I’m presenting a talk in June on monitoring the new anticoagulants. Do you have experience with the PiCT? If so, could you tell me how it works and how effective it is? I’ll give attribution in my presentation, thank you! Geo.
