What is an Antibody Test?

Jun 6, 2021 | 0 comments

As lockdown restrictions begin to ease across NI, mass testing is key to tracking and containing the virus to help keep us on the right trajectory back to normality.

It is important to be aware of the different kinds of testing available, to work out which one is best for you. There are two different strands of testing. One is to determine whether a person is currently infected (antigen and PCR) and the other determines if they have been previously infected. The latter is known as antibody testing.

What is an Antibody Test?

An antibody test detects antibodies in your blood. The antibody test is used to determine whether you have been infected with the Covid-19 virus in the past. The antibody test will work even if you never showed Covid-19 symptoms, which is called asymptomatic infection.

What is an Antibody and why are they important?

Antibodies are deployed by the immune system to fight off a foreign invader such as a virus. Antibodies can help protect you against getting that disease again. However, how long this protection may last is different for each disease and each person and is still yet to be determined for Covid-19.

It is important to note that the body usually takes between 1-3 weeks after the initial infection, to begin creating antibodies. Which means timing an antibody test correctly can be key.

Antibody Test NI

If you are a resident of Northern Ireland, you can complete one of our PCR tests at any of our locations in Derry, at Belfast International Airport at McCausland’s and with our mobile testing unit.

The test is carried out by taking a blood sample. The test results are received in minutes. At JACE Medical our clinic is run by healthcare professionals who are experienced in sampling and testing for COVID-19. Our aim is to improve the testing capacity through NI.

What does a Positive Test Result mean?

A positive result indicates the detection of antibodies in your bloodstream. This means you are likely to have been infected by the Covid-19 virus in the past. It is possible that the presence of these antibodies in your body may help protect you against being reinfected from the Covid-19 virus again. However, at the present moment, it is still unclear how much protection the antibodies provide or how long the protection lasts. A number of reinfection cases have been reported but they remain rare.

Please note that even if you receive a positive antibody test, you should still take every precaution to keep yourself and others safe.

What does a Negative Test  Result Mean?

A negative result means that you are not likely to ever have been infected by the Covid-19 virus. However, it could also mean that you have a current infection or be recently infected. This is because the body typically takes between 1-3 weeks after the initial infection to create antibodies.

It is important to note that some people may take even longer to create antibodies. Others may never develop antibodies.
