New Finger-Prick test could speed up blood clot diagnosis
NCT ID NCT04737954
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a new rapid D-dimer blood test (LumiraDx) in 679 people with symptoms of deep vein thrombosis or pulmonary embolism. The test uses a small blood sample from a finger prick or vein to quickly measure D-dimer levels, which can help rule out dangerous blood clots. Researchers compared the new test's accuracy to standard lab methods to see if it could be a reliable tool for faster diagnosis.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
LumiraDx point-of-care D-dimer assay
What this could lead to
If accurate, this could provide a faster, easier way to rule out dangerous blood clots in the legs or lungs, potentially reducing the need for hospital visits.
What could go wrong
This is a diagnostic accuracy study, not a treatment trial. The test may not be as reliable as standard lab methods, and results depend on proper use and patient selection.
