RT-PCR test - Also called a molecular test, this COVID-19 test detects genetic material of the virus using a lab technique called reverse transcription polymerase chain reaction (RT-PCR). A fluid sample is collected by inserting a long nasal swab (nasopharyngeal swab) into your nostril and taking fluid from the back of your nose.
RT-PCR tests are very accurate when properly performed by our health care professionals.
Antigen test - This COVID-19 test detects certain proteins in the virus using a long nasal swab to get a fluid sample.
A positive antigen test result is considered accurate when instructions are carefully followed, but there's an increased chance of false-negative results — meaning it's possible to be infected with the virus but have a negative result. Depending on the situation, a doctor may recommend a RT-PCR test to confirm a negative antigen test result
