IgG Quantitative Antibody Home Test Kit
Our home testing kit enables you to check your immune system's response to vaccination or past infection in the safety of your own home. Whether you have been recently vaccinated or caught Covid-19 naturally, this test will confirm whether your immune system has developed IgG antibodies and give you a quantitative measure of your body's response (between levels of 0 - 80,000 AU/ml).
We will send your testing kit out with clear insructions and a prepaid return package. The procedure is a very simple finger prick blood test.

What’s in the test kit?
You will receive the following:
- Introduction letter with instructions
- Blood collection tube
- Multiple lancets
- Test request form
- Blood tube holder
- Biohazard plastic bag
- Prepaid tracked return envelope
Please note, it is not yet clear how your immune response relates to whether you are immune or not. Research into this is ongoing so do not presume you are immune - even with a positive result. This virus has not been around for long enough for the scientists to be sure whether or not having IgG antibodies does make you immune - even at high levels. All advise in constantly being updated by the NHS here: https://www.nhs.uk/conditions/coronavirus-covid-19/.
About the test
It will help you to know how your immune system has responded to vaccination or an infection to confirm whether the illness you had was Covid-19 or something else. IgG levels often reduce quite quickly in the months after an infection and this test will enable you to monitor your IgG levels over time to see if your levels are dropping to below the levels that may be assumed to give immunity. If you receive a positive result, this is because the test detected an AU/ml level of above 50 units, which can be taken to confirm that you have been either been exposed to coronavirus or that your body has produced an immune response to your vaccination. This quantitative IgG test measures your levels of IgG antibodies against the spike receptor-binding domain (RBD) of SARS-CoV-2. The spike protein is the main protein that is associated with the body mounting an immune response. It is also the protein which all the immunisations are mimicking to get the body's immune system to fight off the virus so this test will tell you how well your body has responded to the vaccine.
How it works
The finger-prick testing kit willbe delivered to you where you can take your blood sample, register your test and return it to our lab via a supplied Royal Mail 1st Class envelope. We will ship you our easy to use home sample collection kit within a day of your order by post. When you receive it open the package read the letter and information carefully. It is a fairly simple process to provide a blood sample via a finger prick (tutorial video in the section below). Send us your blood sample back using the supplied packaging and return postage. Once we receive it we load your blood sample into our laboratory instrument that detects whether IgG antibodies are present. Your results will be ready within 1-2 days after arriving at our laboratory.
How to do a finger prick test
Your test kit contains easy to follow instructions on how to take your own finger blood sample. However, if you want to see how it works then check out our tutorial video on the finger prick sampling process.
How and when will I get my results
As soon as your sample is tested, we will email you a certificate with your results—a conclusive positive or negative result as to whether enough Covid-19 antibodies were detected in your sample to confirm definitively whether you have either been exposed to the virus or you have responded to the vaccination.
Your results will be ready within 1-2 days after your sample has arrived at our laboratory.
When should I take the test?
This test is best taken at least seven days after your initial coronavirus infection or vaccination. Your levels are likely are to continue to rise up to 15 days when it is 99.4% sensitive in confirming your exposure to the spike protein of the virus.
Shipping is free and no additional costs are required.
