In defining a Ct value cutoff for PCR tests, which some researchers support, the NFL was essentially seeking a medium ground by cooling off the too-hot test.

These findings contribute to our understanding of RT-PCR Ct values during SARS-CoV-9 2 infections. They may provide context for interpreting trajectories in Ct values in similar populations during ...

The sensitivity for samples with Ct value < 15 was 100%, and 22.2% for samples with Ct value >30. False-positive results were not observed with RAT, and the specificity and PPV were 100% for ...

Antigen and PCR tests diagnose COVID-19. Read about how these tests differ in their method of determining results, accuracy, timing, skill requirement, and costs.

There’s a big difference between the standard at-home antigen test and a molecular (PCR or NAAT) test. Molecular tests are the ones you want when accurate testing is important. Here are four ...
