Saliva test to detect Covid-19 performs better than the nasal and oral swab tests authorised by the US Food and Drug administration (FDA), according to a study. The study by Rockefeller University conducted a direct head-to-head comparison of 162 individuals who received both the “DRUL” saliva test and a conventional swab test.
DRUL caught all of the cases that the swabs identified as positive — plus four positive cases that the swabs identified as positive — plus four positive cases that the swabs missed entirely.
“This research confirms that the test we developed is sensitive and safe,” said Robert B. Darnell, Professor and head of the Laboratory of Molecular Neuro-Oncology. “It is inexpensive, has provided excellent surveillance within the Rockefeller community, and has the potential to improve safety in communities as the pandemic drags on,” Darnell added.
