PT/INR Testing: Calibration, Correlation, Concordance

 

PT/INR Testing: Calibration, Correlation, Concordance

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 LabLeaders Webinar, Marcia L. Zucker, Ph.D., ZIVD, LLC, shares valuable information regarding the reasons behind the apparent lack of standardization, evaluating both lab to lab and lab to point-of-care (POC) variability. Importantly, she uncovers ways to mitigate the variability to ensure best patient care practices. You also learn about the history and evolution of PT/INR testing, calibration and its effects, why INR results between methods don't always match, and how to compare results.
