So, how accurate are at-home COVID tests now, how likely are false negatives, and when should you test yourself? Below, two infectious disease doctors break it all down, and answer your most pressing at-home test questions. Meet the experts: Thomas Russo, MD, is a professor and chief ...
At least one team played without their lab results, relying on last-minute negative results from rapid tests instead. But when they finally got their delayed PCR results from the state lab, one player tested "positive" with the state's highly sensitive test. As a result of the state's del...

In pooled testing, laboratories combine samples taken from several people and test the multiple specimens together for the presence of genetic material from the novel coronavirus. If a batch tests negative for COVID-19, all those patients are cleared. If a batch tests...
Sampling conditional on being tested for active COVID-19 infection (Case definition: positive test for COVID-19, Control definition: negative test for COVID-19, Fig.2b): PCR antigen tests are used to confirm a suspected (currently active) COVID-19 infection. Studies that aim to determine th...
