safe covid testing

Check whether your immune system has responded to a Covid-19 infection or your vaccination.

This brand new test (January 2021) “was designed to aid in evaluating the immune status of individuals with quantitative measurement of IgG antibodies against the spike receptor-binding domain (RBD) of SARS-CoV-2.”*
Whether you have been vaccinated or caught Covid-19 naturally, this test will confirm whether your body has produced IgG antibodies and give you a quantitative measure of your body’s response (between levels of 0 – 80,000 AU/ml).
This test can help you to know if you may have been infected without knowing it, whether your illness was covid-19, or to check whether you have responded to vaccination.
Please note though: it is not yet clear whether a positive test definitely means you are immune to further infection (and for how long) as the 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 what the clinical implications are of having IgG antibodies – even at high levels.
It is well known that IgG (and immunity levels) do reduce in the months after infection and this test will enable you to monitor your IgG levels over time if you would like to monitor this.

FAQs

The IgG and IgM antibody tests determine if you have antibodies in your system as a result of being infected with Covid-19 recently or in the past, or as a result of receiving a vaccine. However, these tests do not measure the quantity of IgG antibodies in your system.
With this most recent quantitative test—produced by the world’s leading laboratory diagnostics provider —your sample will be analysed for the level of IgG antibodies in your body. 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 latest IgG test also measures a different viral protein than the previous one (from May 2020). This quantitative IgG test measures your levels of IgG antibodies against the spike receptor-binding domain (RBD) of SARS-CoV-2 whereas the previous test measured IgG against nucleoprotein. 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.
The old IgG test would not measure whether your body has responded to the vaccine whereas this new test does.

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.

It is not yet known how long antibodies last, as research into this is ongoing. There is evidence that people’s immune response to infection drops off significantly over 6-9 months. It is as yet unknown how long your IgG levels remain high after vaccination. This test will be a very valuable tool in helping scientists to monitor this.

No, this test will only determine whether your body produced IgG antibodies in your blood which occur over 7 (and for best results at least 15) days after a Covid-19 infection or a vaccination.
