His office did not reply to repeated requests for comment. Mayor Eric Garcetti said he had hoped that making the tests widely available would reduce the spread of the virus. To reduce the false results, the FDA warns to test "symptomatic individuals within 14 days of COVID-19 symptom onset."īut in Los Angeles and elsewhere, the company often tests non-symptomatic individuals. He added: "This to me is part of a much larger problem than just sending samples to one laboratory." "The challenge is that oral fluid itself is probably not a good source, especially in the asymptomatic patient." If RT-PCR nasal tests are 100% sensitive, he said, oral fluid tests like Curative's are about 80% sensitive. The announcement raises broader questions about the types of tests administered by counties across the nation, Garner said. Omai Garner, the director of clinical microbiology at UCLA, said these warnings are often released in response to complaints. The FDA will continue to review how the test performs for both symptomatic and asymptomatic individuals. Food and Drug Administration warned of that test's "risk of false results, particularly false negative results."Īn FDA spokesperson confirmed to dot.LA that new information prompted the organization to issue the advisory but she would not elaborate. Curative will continue to offer its oral swab test that patients can self-administer from inside their cars. The change will not affect the 10 testing sites supported by the city of L.A., including one at Dodger Stadium.
