Frequently Asked Questions

FAQ For Antibody Testing

What does the Antibody test tell me?
Antibody testing will be able to tell you if you have detectable antibodies to COVID-19 in your blood.

How does the Test Work?
The COVID-19 antibody test looks for the presence of specific antibodies in the blood for the SARS-Cov-2 virus (the virus that causes COVID-19). The presence of antibodies in a blood test helps identify those who have been previously infected by COVID-19. You’ll either receive a positive (antibodies detected) or a negative result (antibodies not detected).


How accurate is the test?
A highly sensitive test should capture nearly all true positive results.  A highly specific test should avoid nearly all false positive results.  This is the testing system we use with a 100% sensitivity and 99.8% specificity.

When is the best time for me to have the test?
The test should be done at least 20 days after:
•    The first day of COVID symptoms if you had symptoms.
•    The day of a positive COVID-19 PCR test result
•    Suspected infection.  If you were told to self-isolate and didn’t get symptoms, then wait 20 days after your self-isolation period has finished.

Or at any point if you have not had symptoms but would like to know if you have detectable antibodies.

What is the maximum time I can wait to have a test?
There is no conclusive evidence to determine the duration of an individual’s antibody response. We are therefore unable to recommend a ‘maximum’ time to wait before having the test. We do however recommend having the test as soon as possible after the 20 days since symptoms began.

Can you tell me what my antibody levels are?
The test provides a positive (antibodies detected) or negative (antibodies not detected) result. It is important to note that we do not yet know whether antibodies offer definitive protection against COVID-19 re-infection, and if so, at what level, or how long for.

How long does it take to get my results?
Results will be back in a couple of days or less via email.

I have symptoms, is this the right test for me?
This test will not tell you if you currently have COVID-19. If you have symptoms, you will need a Covid PCR Test.  The NHS can provide testing if you have symptoms to check if you are currently infected.
If you prefer to have a private PCR test in your own home we can provide this service for you. View details HERE >


If I get a positive result does that mean I’m contagious?

No. This blood test is testing for antibodies for COVID-19. These are best detected over 20 days after infection began. This test therefore does not tell you if you are currently contagious.


Will the Blood Test Hurt?
The Test involves a simple blood test from one of our highly trained Phlebotomists. We take one small bottle of blood from you.  We pride ourselves on our care and reputation as a company.

If I get a positive result, does this mean I am immune to Covid-19?
No.  If you encounter certain viruses the body may produce antibodies to help defend against it, should you come into contact with it again. However, because COVID-19 is a new virus, it is not yet known if the presence of antibodies provides immunity to COVID-19, or for how long any protective immunity may last. Even if you get a positive result you still need to follow government guidelines around social distancing and self-isolation.

Please note:

As an organisation, we do not get involved with any diagnosis or medication.  We are purely a Phlebotomy service, so you would need to take any results to a Doctor or clinician for interpretation.
