Point of Care Testing

Point of care coagulation tests are used in surgical and trauma suites to provide quick results in order to guide transfusion therapy. Coagulation tests sent to a central laboratory may take from 30-60 minutes. The patient's condition can change dramatically in the massively transfused patient and the test results are not representative of the patient when they are reported. In addition, to PT, PTT and INR, thromboelastography (TEG) and thromboelastometry (ROTEM) have been used to assess coagulation and reduce transfusions of plasma as well as other components in patients having aortic or liver transplant procedures.
