What is an Antibody Test?

An antibody test is a looking for things called antibodies in your blood. Your body makes these when it fights an infection, like Covid-19. The same thing happens when you get a vaccine, like a flu jab. That’s how you build immunity to a virus.


The antibody test isn’t checking for the virus itself. Instead, it looks to see whether your immune system (your body’s defence against illness) has responded to the infection. The Finger Prick Antibody test is a ‘self-collect test’ kit which can be carried out from the comfort of your home.

How do I take the Antibody Test?

You’ll have to give some blood, in this instance a Finger Prick Blood sample. A couple of drops of blood is all that is required.

What is the difference between a Coronavirus test and an Antibody Test?

An antibody test shows that you had the virus at some point in the past.

If you have antibodies, then it is thought that you might have some possible level of immunity to coronavirus. That said, we have to wait for further scientific research and data to determine if this is the case.

A coronavirus test, sometimes called a PCR diagnostic test, looks for signs of active virus in your body. It’s simpler and faster than an antibody test. But it tells you only if you have the virus in your body at the moment when you’re tested. These tests are usually carried out using a nasal or throat swab.

When should I get an Antibody Test?

If you have / or think you have experienced the symptoms of coronavirus recently you need to wait at least 14 days from the day the symptoms started before carrying out an antibody test.

How accurate is this test?

The test used in the Laboratory is PHE (Public Health England) evaluated and shows the following:

94.7% Sensitivity on 187 clinical samples collected > 20 days post laboratory confirmation

100% Sensitivity on 58 clinical samples collected >40 days post symptom onset

97% Specificity on 692 samples collected pre- December 2019

When should I expect my results?

It takes approx. 3-5 days to return the result to you once the laboratory receives the sample. This may be quicker or slower depending on laboratory capacity.
