Thus, this is the key difference between antigen and NAAT test. PCR procedure requires special chemicals, primers, and enzymes in order to produce millions of copies of genetic material inside the PCR machine called the thermal cycler. In RT-PCR, reverse transcription is followed by PCR. The enzyme, reverse transcriptase is involved in the synthesis of complementary DNA from RNA. The main difference between PCR and RT-PCR is that PCR uses double-stranded DNA as the template whereas RT-PCR uses RNA as the template. Then, the next step of the NAAT amplifies the genetic material by making many copies of it for detection.

Based on evolving evidence, CDC recommends fully vaccinated people get tested 5-7 days after close contact with a person with suspected or confirmed COVID-19. The key difference between NAAT and PCR is that NAAT is a that amplifies genetic material using several ways, including polymerase chain reaction, strand displacement, or transcription-mediated amplification, while PCR is a method that amplifies genetic material using only thermal cycling. Public health surveillance testing may sample a certain percentage of a specific population to monitor for increasing or decreasing infection rate or to determine the population effect from community interventions. Polymerase chain reaction (PCR) and rapid (antigen) tests for COVID-19 both involve taking a swab. NAAT and RT-PCR tests help doctors identify infections. Additionally, not everyone who has COVID-19 ends up with antibodies, and not everyone who has had COVID-19 has displayed symptoms.
