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. This type of test is a looking for things called antibodies in your blood.  

What an antibody test can tell you: 

An antibody test can tell you if it’s likely you’ve had coronavirus before.

But it does not work for everyone, as some people who’ve had the virus do not have antibodies.

An antibody test does not tell you:

  • if you’re immune to coronavirus 
  • if you can or cannot spread the virus to other people


The results are not intended to replace medical advice, nor should they be used as a full diagnosis, or to prescribe medication without consulting an appropriate medical professional. Laboratory testing will always have a small degree of variability.

What is an IgG Antibody Test?

An antibody test is a looking for things called IgG 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.

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 IgG 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?

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

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

97% Specificity on 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.
