Negative tests are tricky to interpret in part because of the issue of timing. After people are exposed to the coronavirus, they incubate it for several days before testing positive or showing symptoms. In a systematic review of seven studies published in May, researchers at Johns Hopkins University analyzed how long this process typically takes. They found that the most widely used test, called a P.C.R. test, was most likely to come back positive eight days after an exposure to the virus, which tended to coincide with a person’s third day of symptoms. Still, even on this ideal day, the tests came back negative on average in 20 percent of people who later tested positive.
Exactly.
8 days ago would be BEFORE the Raiders game.
