What’s the Difference in COVID-19 Testing?

The majority of us have been affected

2020 has been a very different year for the vast majority of the world much less us North Carolinians! The emergence of COVID 19 (the novel SARS- CoV-2 virus) has taken its toll on every single person that I know. Travel, commerce, businesses and personal lives have been affected in more ways than one. We are learning new things about this virus every single day. Many people with coronavirus are actually without symptoms such as (dry cough, shortness of breath, fever, new loss of taste/smell, nausea, vomiting and diarrhea) just to name a few.


COVID-19 testing

PCR testing

To this end, there is testing available now which is more widespread than when we entered this pandemic. PCR (antigen) testing is the nasal swab testing that we have all heard of and this is for people that display symptoms as it detects those people that currently have the disease and thus should be quarantined to avoid transmission to others. The test results may take as long as 7-10 days (which can prove problematic for some). There is also rapid PCR testing which is very difficult to find as it utilizes the same molecular level analysis of the nasal tract, but the results are given within 15 minutes!


The new antibody test

Then there is the antibody test. This test is used for people that are without any current symptoms of the novel SARS-CoV-2 virus but may have been exposed to someone with the virus in the past. This test is done using a blood assay (typically fingerstick), and the results are given in as quickly as 10 minutes to determine if a person has the antibodies to the virus. If a person has the antibodies this is thought to confer some form of immunity to the virus. I like to think of it as being similar to a vaccine. When you receive a vaccination (inactive virus), the whole point is for your body to mount an immune response to it so that you can fight it if your body sees it again in the future.


We can all play our part

It is important to note that although people may be exposed to the virus, some people may not mount an immune response to the prior infection. This is not frequently the case, but it is good to keep in mind! We can all play a part in helping to stop the spread of infection by wearing masks when out in public, socially distancing and washing our hands. We can all play a part in making a difference at this most challenging time. We will get through this together!!!!
