Laboratory coagulation tests

POCT systems are able to measure the different phases of hemostasis (primary hemostasis, thrombin/fibrin formation, clotting and fibrinolysis). The measurements record complex biological processes. These analytical systems mostly demand a high level of training, interpretative competence and quality assurance. Devices for patient-near global coagulation tests (INR, PTT, ACT) are frequently used for this. The self-management of vitamin K antagonists by patients measuring their own INR has produced very good clinical results.
