Testing for COVID-19 has tremendous value when it comes to trying to contain the spread of the COVID virus. According to

Dr. Joseph Bustamante, Chief Medical Officer at Memorial Healthcare, "The variety of


SARS-Cov-2 Test(the virus that causes COVID-19) available today can

be rather confusing. There are some clear indications as to which test you should get and some not so clear reasons."






There are essentially two broad categories of testing. Covid 19 Antigen Rapid Test (frequently referred to as a rapid test). This test detects protein fragments

specific to the Coronavirus. It can be done in a clinic, doctor's office, or hospital. Turnaround time for results is

usually very quick and in some cases, results can be reported within 15 minutes. The other is PCR testing, which is

considered the "gold standard" in SARS-CoV-2 detection. This test actually detects RNA (or genetic material) that

is specific to the virus and can detect the virus within days of infection, even those who have no symptoms. The test can be

done in a clinic, hospital, or even in your car. Turnaround time is longer, generally in the 2-3 day range but results can be

in as little as 24 hours. When demand is high, results can take a week or longer.






Rapid tests are considered most accurate in a patient who is having symptoms of COVID-19. While the rapid test can get

you results very quickly, the results may not always be accurate. It may meet the situation of false negative or false

positive. In those who don't have symptoms, the false negative rate - meaning my test is negative but I actually have the

disease — can be as high as 50%. This can have tremendous consequences as we try to contain the spread of COVID-19.
