COVID-19 testing, such as a day 2 test, proves to help determine cases of the virus and lessen its spread along the way. Aside from rapid antigen and PCR tests, there is also an antibody or serology test that can help determine if an individual has been infected with the SARS-CoV-2 virus, which causes COVID-19. This test is used by the UK’s National Health Service (NHS) to increase their understanding of how the virus spreads and how it affects people.

It can also determine if the body has developed antibodies to the virus following the COVID-19 vaccination. Besides the COVID test for travel, an antibody test is different from a rapid and PCR test which can tell if a person has an active coronavirus.

An antibody or immunoglobulin is the protein created by the body’s immune system to fight a particular virus or antigen. An antibody or serology test is only available to specific groups. Those who wish to take one can register for an antibody test kit and a home test kit sent directly in the post.

Talk to your doctor about whether an antibody test is necessary. If you have symptoms consistent with COVID-19, but your viral test results are negative, doctors may recommend an antibody test. If you have symptoms consistent with COVID-19 but could not have your viral test done, you can still get one.

Results from an antibody test can take as long as 3 to 7 days, usually sent by text or email. There are different antibody tests, the currently available ones that can assess viral proteins. 

Antibody testing can help learn more about the components of the virus and its spread. It is also significant in understanding immunity against COVID-19, the impact of emerging variants of the virus, and how it can affect the vaccine’s efficacy.
