Sniffing out COVID: new At-Home smell test could spot infections early
NCT ID NCT05040659
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a simple, at-home smell test to see if it can detect COVID-19 infection and track how smell recovers over time. About 1000 adults, including those with known smell loss and healthy volunteers, will use smell cards to rate odor intensity, identification, and discrimination. The goal is to see if this test is a reliable tool for screening and monitoring smell changes related to COVID-19.
