What is a coronavirus antibody test?

This test checks for the presence of IgG antibodies to COVID-19 — which can be detected by taking a blood test 21 days after your symptoms started. It won’t tell you if you currently have an active COVID-19 infection, only if you’ve already been exposed.

Important information

Arrow

What is the coronavirus (COVID-19) antibody test?

This test checks for the presence of COVID-19 antibodies. Your immune system produces IgG antibodies when exposed to the coronavirus strain SARS-CoV-2, which causes the disease COVID-19. These antibodies can be detected by doing a blood test 21 days after your symptoms start. Some people don’t show any symptoms, but this test can still detect the antibodies in your blood.

Arrow

What can and can’t this test tell you?

This test can be used to tell you if you’ve had COVID-19 in the past. It won’t tell you if you currently have COVID-19 or if you can infect others. Antigen testing (nasal and throat swab) is what’s being used by the government to check if you currently have COVID-19 — we don’t offer this form of testing.

How accurate is this coronavirus (COVID-19) antibody test?

Our partner lab (Eurofins County Pathology) has validated this test on finger-prick blood samples. Their research shows 98.5% sensitivity and 99.5% specificity.

  • 98.5% sensitivity: If 1000 people who’ve had COVID-19 do a test, 985 of them will get a positive result.
  • 99.5% specificity: If 1000 people who haven’t had COVID-19 do a test, 995 of them will get a negative result.
While this research only included people who had COVID-19 symptoms, this test can still detect antibodies to COVID-19 if you haven’t had symptoms.

What does CE marking mean?

CE marking means this test meets health and safety requirements within the European Economic Area (EEA).

Arrow

When should I do this test?

Wait at least 21 days after your symptoms started before doing this test — if you do it too early, it can affect the accuracy of your results.

Arrow

Can I do this test if I’ve never had symptoms?

Yes, you can still do this test if you haven’t had symptoms. Research suggests that up to 4 out of 5 people who’ve had COVID-19 have mild or no symptoms at all.

Arrow

Who shouldn’t do this test?

Don’t do this test if you currently have symptoms of COVID-19 — this test won’t tell you if you currently have the virus. If you have symptoms, you should follow the latest government advice. The most common symptoms are a high temperature, and a new, continuous cough.

In rare cases, you might have been infected but not have developed antibodies. This can happen if you have a disease that affects your immune function or if you take immunosuppressants.

Arrow

Will this tell me if I’ve developed immunity to coronavirus (COVID-19)?

This test can’t tell you if you’re now immune to COVID-19. This is still a very new virus, and we don’t know how long these antibodies stay in your system. This is why it’s important to continue to follow government guidelines on social distancing.

Arrow

How quickly will I get the results?

Once your sample arrives at the lab, your results should be available online within 3-4 days. Due to possible postal delays, we recommend only doing your test on a Monday or Tuesday and to post your sample in a priority post box if you have access to one.

Arrow

Can I buy multiple testing kits?

No, you can only buy one test per person so you’ll have to purchase tests individually. Also, the name and date of birth you input when purchasing the test has to match what’s on your sample tube label (part of your testing kit). If these don’t match, the lab can’t legally process the sample.

What happens if the test shows I have COVID-19 antibodies?

This test doesn’t include the doctor’s report and personalised advice we usually provide. If you need additional support, please follow the advice from the NHS and government guidelines.
