![]() 2, Curative administered 24,241 tests at these county-supported sites, about 10% of all coronavirus tests administered at such sites during that time frame, the County Department of Health and Human Services said in a statement Sunday.Ĭounty officials said they were discontinuing the use of the Curative tests "as a precaution" and would replace them with tests by Fulgent Genetics. In mid-December, however, Curative began supplying tests at mobile testing sites supported by the county. Public Health Director Barbara Ferrer said at the time that nasal tests produced fewer false negatives. County discontinued its use of Curative's oral swab testing at its main testing sites. He said that about one-third of the positive test results from the city’s program - about 92,000 - were from people without symptoms. While the Curative test is designed for screening people who are visibly ill, he added that the tests are also effective at catching cases in people who are asymptomatic. Responding to the FDA guidance last week, Garcetti strongly backed the testing. Los Angeles has been using the tests since April. To reduce the risk of false negatives, the Curative test should be used only on “symptomatic individuals within 14 days of COVID-19 symptom onset,” and the swab should be observed and directed by a healthcare worker, the FDA said. Guidance issued last week from the Food and Drug Administration warned healthcare providers and patients that the test made by Curative carries a “risk of false results, particularly false negative results.” ![]() Garcetti has defended the tests as broadly effective and said that moving away from them could lead to fewer people being diagnosed and greater spread of the virus. The use of Curative oral swab tests at the city of Los Angeles' drive-through testing sites are unaffected by Sunday's decision, although Mayor Eric Garcetti's office said separately that the Dodger Stadium site would be turned into a vaccine distribution center this week, ending testing operations there Monday. County health officials had already discontinued the broad use of oral swab tests produced by Silicon Valley start-up Curative over the summer because of concerns about too many false negatives. The decision affects only a small number of county-supported mobile testing sites. Los Angeles County health officials said Sunday they will stop providing a commonly used coronavirus test after federal regulators raised questions about its accuracy.
