Same Day RT-PCR, Rapid Antigen COVID-19 & Flu Testing in Union Square, San Francisco

The RT-PCR test is processed at a high-complexity laboratory and is generally much more accurate than the Antigen test. The RT-PCR test recognizes the virus DNA itself, whereas the Antigen test recognizes the protein made by the virus. As such, the RT-PCR test is able to recognize the virus at a much earlier stage after exposure, whereas the Rapid Antigen test detects the presence of the virus at a later stage.

For patients that don’t have any symptoms and were exposed, we generally recommend the RT-PCR test.

We provide the RT-PCR test, which is the most accurate test and is accepted by most travel destinations.

We also provide Rapid Antigen tests, which provide speedy results but are less accurate than the RT-PCR tests.
