What are the COVID-19 Rapid Tests?
Antigen Rapid Test
The COVID-19 antigen rapid test is a Sofia Antigen test that is manufactured by the Quidel Corporation. According to the FDA, the antigen rapid test COVID detects the virus by looking for proteins from the virus. This test is a highly specific test, but less sensitive than the molecular tests.
Molecular Rapid Test
Rapid Testing offers two types of COVID-19 molecular rapid tests: Abbott ID NOW and Cepheid RT-PCR. In general, molecular tests detect the virus by looking for genetic material from the virus. Molecular tests are highly sensitive and highly specific. The Abbott ID NOW and RT-PCR tests are also known as an NAAT test (nucleic acid amplification test). These NAAT-approved tests are widely accepted by airlines that require an NAAT test.
According to Abbott, the ID NOW molecular test uses “isothermal technology, proprietary enzymes, and constant temperature control to achieve the fastest available RNA amplification.”
The Cepheid RT-PCR rapid test is very similar, but it does not use heat and the test takes a little bit longer to process. Even though the rapid RT-PCR test takes a little longer to process than the Abbott ID NOW test, the results are still same-day.
If your test is for travel, please verify with your destination of travel which test(s) are accepted for your travel itinerary. Every country and state has different requirements. We apologize, but Rapid Testing and Advanced Urgent Care & Occupational Medicine are not responsible if the incorrect test is ordered.
