New fingerstick test for blood thinner monitoring put to the test
NCT ID NCT03682419
First seen Jun 17, 2026 · Last updated Jun 20, 2026 · Updated 1 time
Summary
This study tested how well a small, portable device (LumiraDx) measures blood clotting (INR) compared to standard lab tests. Researchers collected blood from 420 adults, some taking warfarin and some not, using both a fingerstick and a vein draw. The goal was to see if the device is accurate enough for use in clinics, potentially making it easier to monitor patients on blood thinners.

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 could provide a faster, easier way to monitor blood clotting in clinics, helping manage medications like warfarin more conveniently.
What could go wrong
This is a completed device accuracy study, not a treatment trial. It does not test any new therapy or health outcome, so its impact is limited to improving monitoring, not curing disease.
