Blood Donation for the development and optimisation of the second generation Microvisk INR testing system for the measurement of PT/INR in patients on Warfarin Therapy.

Research summary

The overall aim of this research is utilise blood donated from patients on warfarin therapy to aid the development and optimisation of Microvisk’s second generation Prothrombin/International Normalized Ratio (PT/INR) Test System. The donated blood will be used on ongoing development, validation, verification, and calibration projects. Microvisk has developed a small hand-held device which will measure PT/INR from a low volume capillary blood sample. The device is intended for use by both healthcare professionals and for self-testing by the patient. Consenting patients of either sex and all ethnicities over the age of 18 who require PT/INR testing for the purpose of monitoring their oral anticoagulant therapy are eligible to participate in the study. This blood collection will be conducted at multiple sites, primarily being the Haemophilia and Thrombosis Centre at Oxford University Hospital. The blood samples will be transported to Microvisk’s own laboratory for evaluation. Participants attending the centre as part of their routine care will donate additional tubes of blood taken from the same venepuncture as the one used for the collection of blood for local measurement of PT/INR as part of their standard care.
