Our BSC team here in NYC has been deploying a variety of COVID 19 testing solutions to local businesses and it has been a learning experience for us all. Here is a quick tip sheet to help understand some of the common testing options available today:
Standard PCR Test - Used to detect the virus’ genetic material. This is a diagnostic test used to confirm active infections and is considered by the CDC to be the gold standard of tests. The test is generally administered with a nasal swab.
-
Results are slower - tests must be processed at the lab which means public testing facilities quickly get overwhelmed and result times start to vary significantly. Results can take 2 days to over two weeks
-
High Accuracy - negative results do not need a second test
-
Usually covered by insurance
-
Generally done via a nose or throat swab (though some saliva tests are now available)
Rapid Antigen Test - Also a diagnostic test used to detect active infections but this tests looks for particular proteins on the surface of the virus
-
High speed - results can take minutes and be done on site
-
Less reliable results - while false positives are rare, some sources suggest that as many as half of negative results are false. Negative results may require additional tests
-
Pain Threshold - this test is available via nasal or throat swab
Antibody Test or Serology Test - This test is not diagnostic and looks for the presence of the virus’ antibodies. This will establish whether a person has been exposed to the virus which may mean they are less susceptible to reinfection (though the question of immunity is far from settled at this time).
-
Results are fast and usually received on the same day
-
Tests require a blood draw or finger stick
