While other diagnostic tests for COVID-19, known as PCR tests, look for genetic material from the virus, the antigen test looks for molecules on the surface of the virus. PCR tests require expensive and specialized equipment and can take hours or days to get results.

RT-PCR is currently the gold standard frontline test for the diagnosis of Covid-19. Like RT-PCR, the rapid antigen detection test too seeks to detect the virus rather than the antibodies produced by the body. While the mechanism is different, the most significant difference between the two is time.

The lateral flow antigen test can detect the presence of Covid-19 viral antigens after the onset of symptoms or from 14 days after initial exposure to the virus. This means that anyone testing positive can be quickly isolated to avoid further spread.
