Diagnostic Accuracy Study of a Point-of-Care Test for Coagulation Function

Intraoperative coagulopathies in complex procedures are common. For the diagnosis and adequate therapy, laboratory tests are necessary, which can delay the patient's therapy. In this sense, the study aims to evaluate the point-of-care test device for patients undergoing surgeries with cardiopulmonary bypass. Objective: To analyze the accuracy between the point-of-care diagnostic method and the laboratory test considered the gold standard for checking the INR. Methodology: Cross-sectional study of diagnostic accuracy with simultaneous testing of the Coaguchek XS device and standard laboratory method in patients undergoing cardiopulmonary bypass to evaluate INR results.
