Comparing Point of Care Clotting Tests in the OR Versus Standard Laboratory Clotting Tests
Comparison Between Point of Care INR and aPTT Hemochron Jr Whole Blood Measurement With Standard Laboratory in Patients Having Elective First Time on Pump Coronary Artery Bypass Grafting (CABG)

The purpose of this study is determine the agreement of point of care (POC) clotting tests (INR and aPTT) by the POC device by Hemochron Jr versus standard laboratory clotting tests (INR and aPTT) in patients undergoing elective cardiac surgery.

The study is a correlation between POC Hemochron Jr INR and aPTT with the standard.
