Understanding the Different Covid-19 Tests

Typically, there are a variety of screening and diagnostic tests for Covid-19 to suit the different needs. Some of these tests may include the PCR test, ART test and Serology test. And there are administered depending on your needs. Actually, all of these tests tend to be significant in performing Covid-19 tests. So, keep reading to find out the different forms of Covid-19 tests available.

 

Covid-19 Antigen Rapid Test

ART test (new)is normally a faster test to discover viral proteins in the secretions of the person’s mucosal surface. It’s a point of care test done at events and also used as part of the enhanced swab for patients with ARI symptoms. While using the Antigen Rapid Test, a trained staff takes specimens from the anterior nasal space with a swab stick and it’s more comfortable as the depth of the insertion is only about 2cm. After the swab, the staff will then insert a stick into an extraction tube with a buffer solution and drip the specimen onto a cassette.

 

The ART test is well suited as a POCT for pre-event testing due to its short turnaround time. While using the ART in testing, clients are more likely to get their results within a short period of being swabbed and they can go about with their business with some peace of mind. Because of the swab process, ART tends to be less uncomfortable than other test. Plus, ART may not be able to detect patients with low viral loads.

 

Covid-19 Serology Test

Serology tests always involve taking of a blood sample to test for antibodies to the Covid-19 virus. Although it is not employed as a diagnostic test to detect actively infective individuals, Serology tests are mainly used for checking the evidence of previous infections or used for pre-departure screening if required by destination country. The Serology test is typically convenient as it can be done anywhere.

 

During the test process, a trained phlebotomist will draw blood from your veins and then send the samples off to the laboratory for testing. Andyou can certainly get back your results within 24 hours. Just like ART, Serology tests also have its limitations. Serology tests usually have a window period in which a person infected with Covid-19 may not test positive as the antibodies always take time to produce.

 

Keep in mind there are other COVID-19 tests other than the ones mentioned above.
