Could a Finger-Prick test replace clinic blood draws for arthritis patients?
NCT ID NCT07660029
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing a new device called BloodTrackR that lets people with rheumatoid arthritis collect a small blood sample at home using a finger prick and a smartphone app. Twenty participants will try the device and answer questions about how easy it is to use. The goal is to see if home samples are as good as those taken in a clinic, which could make remote monitoring easier.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this device could allow rheumatoid arthritis patients to monitor their condition from home, reducing the need for clinic visits.
- What could go wrong
- This is a very small early study (20 people) focused on usability, not on treating the disease. The device may not be accurate or easy enough for widespread use.
