Once taken, the tests are sent to a laboratory and analyzed to detect COVID-19. Test results for molecular tests have a turnaround time of 1-3 days. PCR/NAAT/TMA tests are effective at detecting a current infection.

Understanding COVID-19 PCR Testing

Aug 31, 2021·What do results mean for a COVID-19 PCR test? A positive result happens when the SARS-CoV-2 primers match the DNA in the sample and the sequence is amplified, creating millions of copies. This means the sample is from an infected individual. The primers only amplify genetic material from the virus, so it is unlikely a sample will be positive if viral RNA is not …
