Nevada health officials are ordering nursing homes to stop using two rapid antigen coronavirus tests due to inaccuracies in the results.

In a directive last week, the state's Department of Health and Human Services (DHHS) cited the Quidel Sofia II and the Becton Dickinson (BD) Veritor Plus.

The tests were hailed a cheaper, similar and faster than traditional laboratory tests with samples that could be processed in as little as 15 minutes.  

However, nearly two-thirds of the tests were false-positive, or people mistakenly told they were infected with COVID-19. 

Nursing homes are asked to longer use the kits 'until the accuracy of the tests can be better evaluated' and use other tests available to them.

There are two different types of tests: nucleic acid tests and antigen tests.
