Rapid COVID-19 test put to the test in Real-World clinics
NCT ID NCT05506618
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study evaluates how well the LumiraDx SARS-CoV-2 Ag ULTRA test detects COVID-19 when used at point-of-care locations like clinics or pharmacies. Participants with COVID-19 symptoms provide nasal and nasopharyngeal swabs, and the test results are compared to a standard lab reference method. The goal is to see if this rapid test can reliably identify infections quickly and accurately.
