Easier-to-Use Coronavirus Saliva Tests Start to Catch On

Kaiser Health News looks at the trend to use saliva tests for coronavirus testing.

Eight months into the pandemic, the move toward saliva screening is gaining traction, with tens of thousands of people across the country undergoing such testing daily. However, saliva tests still represented only a small percentage of the more than 900,000 tests conducted daily on average at the end of September.

Like tests using nasopharyngeal and other kinds of nasal swabs, these saliva tests are based on PCR technology, which amplifies small amounts of viral genetic material to facilitate detection.
