NCT ID NCT04578509

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested whether saliva samples can detect the COVID-19 virus as well as the standard nose swab test. Over 5,000 people provided both nose swabs and saliva samples, which were compared using different detection methods. The goal was to see if a simpler, less invasive spit test could be used for widespread screening.
