About the COVID-19 antibody test kit

  • Our COVID-19 sampling kits are fully regulated

    • Sampling kits include are CE-marked which means they conform to European standards for medical testing
    • Roche antibody test
    • They are legal to supply in the UK
    • The Doctors Laboratory (TDL) provides UK-accredited medical services globally
  • How accurate is the antibody test?

    The antibody blood test has a specificity of 100% and sensitivity of 91%. This means that:

    • If the result is positive, you have COVID-19 antibodies.     
    • Out of 100 people with COVID-19 antibodies, 91 will test positive but 9 will test negative (a false negative). False negatives can be due to low levels of antibodies. 
  • How does the COVID-19 antibody test work?

    The antibody test works by analysing a sample of your blood to test for the presence of COVID-19 antibodies. 

    An antibody is a protein that the body produces to help fight infection. If you have had COVID-19 or the COVID-19 vaccine your body will have produced specific antibodies to fight off the virus. 

  • Do I need a COVID-19 antibody test?

    If you think you’ve had COVID-19 in the past, this antibody test can confirm this. Please note a positive result can be either because you've previously had the virus or received the vaccine.  

    If you think you currently have COVID-19, you might want to get a COVID-19 swab test, which will confirm if you have the virus now. 

  • Using the COVID-19 antibody test kit

    To collect the sample from the antibody COVID test you will need to prick your little finger to produce blood. It’s important you follow the instructions provided in the kit very closely. We’ve also created a handy step-by-step guide below. 

  • Understanding your antibody test results

    Taking an antibody test will let you know if it’s likely you’ve had COVID-19 in the past.

    What does a positive result mean? 
    A positive result means that there were COVID-19 antibodies in your blood sample. This can be because you've previously had the virus or received the COVID-19 vaccine.

    Please note, not all people with antibodies will test positive. 9 out of 100 people with antibodies will test negative, also known as a as a ‘false negative’. This can be due to low levels of antibodies in your body. 

    If I have a positive result for antibodies, am I immune from COVID-19?
    No, unfortunately, testing positive for antibodies doesn’t mean you’re immune from COVID-19. 

    A positive result for antibodies:

    • Means you have been exposed to COVID-19 in the past
    • Doesn’t mean you’re completely immune
    • Doesn’t mean you can’t spread the virus to other people

    If you test positive for antibodies you still need to follow social distancing guidelines and the restrictions in your local area. 

    What does a negative result mean?
    Testing negative for COVID-19 antibodies means that there were no antibodies in your blood sample. This means you most likely haven’t had COVID-19. 

    Please note, 9 out of 100 people with antibodies will test negative. This is called a ‘false negative’ and can be due to low levels of antibodies in your body.

      Will I get my result instantly?

      Should I take this test even if I didn't have COVID-19 symptoms?

      You can take the antibody test whether you have had symptoms or not. 

      Please note, a positive result on an antibody test does not confirm immunity. You should follow government guidance on local lockdown restrictions, social distancing and self isolation if you or someone in your household/bubble develops symptoms. 

      Does the COVID-19 antibody test tell me if I’m immune from the virus?

      No, this test cannot tell you if you have immunity. The test simply confirms that you have been exposed to the virus or not. 

      A positive result means that there were COVID-19 antibodies in your blood sample. This can be because you've previously had the virus or received the COVID-19 vaccine.

      When will my COVID-19 antibody blood sampling kit arrive?

      Your sampling kit will arrive within 2 working days of your order being approved by our clinicians.

      Your sampling kit will come with packaging and prepaid postage, so you can send your sample back to our partner lab.

      How will I receive my COVID-19 antibody results?

      Once the lab has received your sample, it usually takes 2 working days for them to process your results. 

      The lab will send your results back to us and we will send you an email (and text if you have opted in to receive SMS updates) to let you know that your results are ready. You will need to log into your account and your results will be in your Patient Record.

      What happens if I test negative for COVID-19 antibodies?

      If your result is negative, this means COVID-19 antibodies were not present in your blood sample at this time.  

      Please note out of 100 people with COVID-19 antibodies, 9 will test negative. This is a false negative. 

      What happens if I test positive for COVID-19 antibodies?

      If your result is positive, this means COVID-19 antibodies were detected in your sample. This means you’ve been exposed to COVID-19 in the past.
