Many people are perhaps familiar with diagnostic tests for COVID-19 that detect the viral DNA and proteins specific to the virus,such as Polymerase Chain Reaction PCR and rapid antigen test. Both tests are essential to preventing the further spread of the virus and the immediate isolation of infected individuals.
However, only a few people know the serology tests for coronavirus. Unlike the PCR and rapid antigen test that can determine if an individual has an active coronavirus infection, a serology test can tell whether a person has been previously infected with COVID-19.
A serology or antibody test aims to look for antibodies developed in response to an infection, and in this case, COVID-19, by analysing a blood sample. Aside from identifying people with coronavirus infection in the past, antibody tests can also help the NHS and scientists learn more about the virus and its spread.
Additionally, it is beneficial in understanding immunity against COVID-19, the impact of new emerging variants,and how effective the vaccine is. For people who want to get an antibody test, it is essential to note that it is only available to specific groups. Individuals who wish to take one might be eligible to register for an antibody test if they take part in the following:
Alternatively, people can ask a doctor if taking one is appropriate. Doctors can recommend getting one should an individual develop symptoms consistent with COVID-19 despite a negative viral test. People who got a negative antibody test mean that the test did not detect any COVID-19 antibodies. Still, antibodies take time to develop.
If you want to get tested for COVID-19, you can now opt to order home PCR tests for convenience. But it is important to remember that you should only order from a government-approved provider.
