"The C3 Test is able to detect really low levels of viral RNA, which means that even if you have a little bit of coronavirus, it'll still know that you have it," a spokesperson for the Mailman School of Public Health tells Refinery29. "It cuts down not only on false negatives but it also cuts down false positives. So if you have the flu or something else, you're not as likely to get a false positive, which means that people who don't have COVID-19 don't have to be quarantined for no reason."
