LOS ANGELES — At-home coronavirus screening has become a way of life for many Californians, but some medical experts are now cautioning that one test may not be enough to definitively determine whether someone is infected.
Health officials stress that at-home tests are a vital and accurate way of tracking COVID-19 infections but an initial negative test doesn’t mean people are out of the woods.
The U.S. Food and Drug Administration suggested last week that those checking to determine whether they are infected should use multiple tests over a period of days.
