Rapid Antigen Tests (RAT) has been performed on a large scale and have helped in a significant increase in testing in the country and especially in the national capital Delhi. However, being performed on a large scale doesn’t mean a person should rely completely on this test’s result, as the positivity rate of RAT is showing a decline in cases of COVID-19.

Therefore, Health Department Officials suggest that a person should go for an RT-PCR test too because the RT-PCR test detects the virus’s genetic material, whereas antigen tests detect specific proteins on the surface of the virus.
