Washington University develops COVID-19 saliva test

View Content

A new saliva test to detect the SARS-CoV-2 virus has been developed by researchers at Washington University School of Medicine in St. Louis. Results from the COVID-19 diagnostic test are available in a few hours and, ideally, able to be communicated to people tested within a day. Highly sensitive to detecting even tiny levels of the virus in a saliva sample, the test does not require special swabs and reagents that have been in short supply.
