BloodTrackR Usability and Concordance Study (BUCS): Evaluating a Smart Home-Based Blood Collection Platform for Remote Monitoring in Rheumatoid Arthritis

The BloodTrackR Usability and Concordance Study (BUCS) is evaluating a novel home-based blood collection device and companion mobile application for people with rheumatoid arthritis. Participants will use the BloodTrackR device to collect a finger-prick blood sample at home and complete symptom assessments through the app. The study will assess how easy the device and app are to use, whether participants can successfully collect high-quality blood samples outside of a healthcare setting, and how closely the results compare with standard venous blood samples collected by a phlebotomist. Findings will help determine the potential of BloodTrackR to support remote monitoring and reduce reliance on NHS phlebotomy services.
