NEW YORK ─ The Yale School of Public Health is preparing a submission for Emergency Use Authorization from the US Food and Drug Administration for an RNA extraction-free saliva assay that can be used as an alternative to nasopharyngeal swabs.
Saliva is less invasive than nasopharyngeal swabs and has the potential to enable greater consistency in test results, said Anne Wyllie, an associate research scientist at the Yale School of Public Health, who is one of the test developers.
