A coagulation analyzer can be used to measure a coagulation pathway speed, as well as thrombin and thromboplastin levels in as low as a few minutes. A coagulation analyzer is specifically designed to handle a large number of patients. To expedite assay completion and proper identifications, these micro coagulation systems employ cuvettes that are bar-coded, obviating the need to separately encode each test sample. With the sensitive nature of patient health information, a micro coagulation system comes with built-in quality control and security lockout protocols to ensure safe and secure use.
