LOS ANGELES – The nation’s second-largest city said it will keep using a coronavirus test that federal regulators warned may produce false results while Congress, which has used the same test, is seeking an alternative.The different responses Thursday followed a Food and Drug Administration alert to patients and health care providers that Curative’s test, which is used in some of the nation's largest cities, could particularly produce false negatives.
Those faulty results pose the biggest risk from a health perspective because people who are erroneously told they don’t have the virus can unknowingly spread it.The warning comes as California copes with its worst surge of the pandemic and some of the highest levels of COVID-19 in the country..
