This easy-to-use finger-prick test can be taken before or after vaccination to see if you’ve had coronavirus before or to give you more information about your body’s response to getting the vaccine.
Our partner lab does this by analysing your level of spike antibodies to work out a number that accurately shows your immune response. Our doctors will then let you know your results confidentially through your patient account.
Our antibody tests are fully accredited and have a CE-MARK. The CE mark confirms that the device is in compliance with the European Directives applicable to the product; which in this case is the Medical Devices Directive 93/42/EEC.
Our laboratory analysis shows they have a sensitivity of 99.98% and a specificity of 98.8%. This means that:
Place an order and a blood collection pack will be delivered to your door. Send your blood sample to our partner lab for testing. Results will be sent to your account within 2 days of receipt of the lab.

Using our antibody testing service:
Anyone over the age of 18 can take a coronavirus antibody test. If you are taking this test because you had symptoms recently, you should only take this test 14 days after they started because your body may not have built an antibody response before this. Otherwise, you can take this test anytime.
Symptoms of COVID-19 include:
Other symptoms include:
Coronavirus testing is very important for key workers, and people supporting those who are in at-risk groups to make sure they can go to work safely.
You can order a coronavirus antibody test kit if you have never had symptoms of coronavirus and want to find out if you’ve been infected previously and been asymptomatic (didn’t show visible symptoms).
We can provide antibody testing if you have already been vaccinated and want to see the vaccine’s effects on your spike antibody levels. However, your results may be affected by a number of different factors.
If you have been vaccinated and receive a negative result for antibodies, this may be caused by:
Try to remember that a negative result does not always mean you haven’t responded to the vaccine. Immune responses after infection involve other immune pathways than just these antibodies. This includes cellular immunity (B and T cells), which are not analysed by this antibody test.
So, if you receive a negative antibody result after only having one dose of the vaccine, you should continue to get your second dose as planned.
This antibody test is a laboratory-based blood test. This means that you collect a blood sample using a lancet by pricking your finger. This sample is then sent to our fully-accredited partner laboratory in the UK for testing and analysis.
You must collect your sample no earlier than 2 weeks after you first started showing symptoms that may have been related to coronavirus. If you haven’t had any symptoms recently, or at all, you can collect your blood sample at any time. This is because if you collect your sample within the first 14 days of showing symptoms, you may not have produced an antibody response, so your test may come back negative even though you have the virus.
This test will only tell you if you’ve already had coronavirus if you’ve developed enough antibodies as a response to it. This test will not tell you if you currently have the virus or whether you are still infectious to other people. If you need to find out if you currently have the virus, you need to take a PCR swab test.
The laboratory we’re partnered with currently reports that our antibody tests detect 99.98% of cases if the person taking the test has developed antibodies. If the person taking the test did not develop a strong enough antibody response, or their levels of antibodies have dropped, the test might not be able to tell you if you’ve had coronavirus before.
The reports from the laboratory show that these tests have a sensitivity of 99.98% and a specificity of 98.8%. This means that:
These tests are completely legal to sell in the UK and have a CE-mark to prove their authenticity.
Do the NHS need these tests?
We are using a very small portion of our partner laboratory’s capacity, which is not being used by the NHS at the moment. Due to this, our testing service in no way harms the national testing effort. If this changes, we’ll work with our partner lab to make sure we’re fully supporting the NHS.
The price of this test covers the entire testing service, which includes:
If you have any further questions for our doctors, you can message one for free through your patient account.
Once the lab has received your sample, you should get your results within 1-2 days, which you will receive in your patient account.
Positive test results
If you test positive for coronavirus antibodies, it means that you have been previously infected with the virus, and may have some immunity. However, we do not know how long any immunity lasts or how strong it is, and you might be able to carry the virus and pass it on. Due to this, you must still follow the rules of social distancing to make sure you don’t spread the virus to vulnerable people or catch it again.
Does a negative result mean I've not had coronavirus?
If you’ve not had typical Covid-19 symptoms before, then a negative result probably means you’ve not been infected. But, if you think you have previously had typical COVID-19 symptoms but have a negative antibody result, it may be that you have not had a sufficient immune response to it, or your antibody levels have dropped since your infection. It’s impossible to say who these people are without testing for antibodies. There is some evidence to suggest that antibody levels in some people may drop to undetectable levels some time after infection, but other parts of the immune system stay active. These B cells and T cells might provide some level of immunity, but we don't have tests for them yet, and we don't know what level of immunity they might provide. There are other tests which are being developed that might give a better indication of past infection, but these are in a research phase. Once they become available, we’ll let you know.
If you develop symptoms after taking your test, you should self-isolate. If you’re feeling very unwell or are concerned about your symptoms, you should contact your GP or call NHS 111.
Do I still need to follow social distancing if I test positive for antibodies?
You must still follow the rules of social distancing as we do not know how well our antibodies work against fighting another coronavirus infection. You may be able to fight it to some extent, but we can’t be sure. We also do not know how long your immunity will last. So until we do, you must continue social distancing, especially because even if you have immunity, you may still be able to spread the virus.
