Blood Donation From Warfarin Users for the Development of POC INR Monitor
Blood Donation for the Development and Optimisation of the Second Generation Microvisk International Normalized Ratio (INR) Testing System for the Measurement of Prothrombin Time (PT)/INR in Patients on Warfarin Therapy.

Descrizione dettagliata
The number of patients receiving anticoagulation therapy with warfarin and other vitamin K antagonists has been rising in recent years. Increasing life expectancy is increasing the proportion of the population having conditions such as Atrial Fibrillation and venous thrombosis, where primary and secondary prevention of thromboembolic complications are best achieved with anticoagulation.
Unpredictable pharmacokinetics, widespread interactions with drugs and food and the narrow therapeutic window make closely monitoring Vitamin K antagonists a necessity. Portable point of care (POC) coagulometers which measure PT from capillary whole blood and provide an INR reading within a few minutes are already widely available throughout North American and Europe. They give comparable results when compared to laboratory based systems are popular with patients and significantly shorten the duration of clinics. In addition, the United Kingdom Department of Health has been encouraging the use of anticoagulation services in Primary Care Trusts the aim being to provide INR monitoring in community clinics and General Practice surgeries relieving pressure on hospital services and reducing inconvenience for patients.
Although coagulometers are now commercially available the Microvisk INR Testing System has been designed to have advantages, particularly in terms of test robustness, user comfort, ease of use and reduction of user error. The present trial has been designed to develop the second generation Microvisk INR Test System; blood samples will also be used to optimise manufacturing processes and verify the quality of Test Strip Lots.

The Primary Outcome will be measured in terms of differences in International Normalised Ratio when the Generation 2 system is tested against the Generation 1 system using the blood samples from the same donors.
Those differences will be reported in terms of accuracy, precision and sensitivity to interferents.
