New rapid test could spot flu and RSV in minutes at your local clinic
NCT ID NCT04288921
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new rapid test (LumiraDx Influenza A/B + RSV Test) that uses a nasal swab to quickly detect flu A, flu B, and RSV. Over 500 people with cold or flu-like symptoms took part. The test was performed by healthcare workers at point-of-care sites and compared to standard lab methods to see how accurate it is.
