The Centers for Disease Control revised their guidelines this week; saying some PCR tests for COVID-19 could “stay positive for up to 12 weeks.”
“So we would have people in isolation for a very long time if we were relying on PCRs,” said CDC Director Rochelle Walensky.
“We do know that the most sensitive test you can do is a PCR test,” Walensky added. “So if you have symptoms and you have a negative antigen test, we do ask you to go and get a PCR to make sure those symptoms are not attributable to COVID.”
