Coronavirus (COVID-19) Antibody Testing.

The Randox health antibody testing service can help determine whether you’ve previously had coronavirus (COVID-19).  This simple blood test is designed to detect COVID-19 antibodies and is carried out by a clinician in our health clinics, aiming to give you a result within 3-5 days.


Our highly accurate antibody test can be purchased as a stand-alone test, as an ‘add-on’ to our popular Everyman / Everywoman packages or as part of our exclusive Signature package.


If you are worried you have a current COVID-19 infection, the antibody test can be purchased in combination with our PCR (diagnostic) home testing kit. To find out more click here.

Antibody Testing



Antibodies are produced by the body in response to infection.  A positive antibody test result indicates that you have previously had the COVID-19 infection.  A negative result indicates that it is unlikely you have been infected with the virus.  Please note that in some cases, people who have previously had the virus have not tested positive on the antibody test.


The Randox Health antibody test does not tell you:

  • If you have immunity to Coronavirus (COVID-19)
  • If you can or cannot spread the virus to other people


It is also important to note that regardless of your result you will still need to follow the government guidelines around social distancing and self-isolation.



1. How is the antibody test carried out?

Although home tests kits are available on some websites, the most reliable antibody tests are performed in the laboratory. A simple blood test will be taken at one of our clinics and sent to the lab for analysis.


2. What does a positive result mean?

A positive result indicates that you have antibodies to SARS-CoV-2 in your blood. This means it is highly likely that you have been infected with the virus in the past.


3. Does a positive antibody test mean I am immune to COVID-19?

It is not yet known if the presence of antibodies to SARS-CoV-2, the virus that causes COVID-19, means an individual has lasting immunity. This will become clearer over the next few months as we learn more about the virus.


4. What does a negative result mean?

A negative result indicates that you do not have antibodies to SARS-COV-2 in your blood. This means it is unlikely that you have had COVID-19. However, it is important to note that a negative antibody result could mean that you have taken the test too soon after developing symptoms. It can take at least 14 days for the body to produce antibodies at detectable levels.


5. Will a coronavirus antibody test tell me if I have a current infection?

No. The antibody test will not detect a current infection. Antibodies are produced some time after an individual becomes infected.
