Xprecia Prime™ is the new and improved generation of portable coagulation monitoring device. Xprecia Prime™ is small, accurate, and easy to use. This new coagulation analyzer is designed for fast and reliable PT/INR testing, allowing medical practitioners to monitor vitamin K antagonist oral anticoagulation therapy (e.g. Warfarin, Coumadin etc.) at the point of care (POC), primary care, urgent care, and hospitals. It should not be used to measure PT/INR in patients on other anticoagulation therapies. Xprecia Prime™ meets the modern high-quality POC coagulation testing requirements, providing PT/INR results comparable to laboratory analysis in under a minute.
