Monitoring oral anticoagulation patients can be complex as frequent monitoring is required to minimize the risk of bleeding or thrombosis (clotting). The INR (International Normalized Ratio) was developed to standardize the tests used to monitor these patients, but falls shy of true standardization. In this talk, Dr. Marcia L. Zucker will cover the reasons behind this apparent lack of standardization, evaluating both lab to lab and lab to POC variability and discuss ways to mitigate the variability to ensure best patient care practices.

What you will learn

  • The history and evolution of PT/INR testing
  • PT/INR calibration and its effects
  • Why INR results between methods don’t always match and how to compare results
