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.
In August 2020, nursing homes in Nevada were sent two rapid antigen COVID-19 tests: the Quidel Sofia II (pictured) and the BD Veritor Plus, but soon started receiving conflicting results when positive tests were checked with nasal swab tests
Nevada health officials ordered nursing homes to stop using the tests after 39 positive kits sent for confirmatory tests, 23 were false positives, meaning an error rate of 60%. Pictured: BD Veritor Plus antigen test kit
There are two different types of tests: nucleic acid tests and antigen tests.
