The home test uses a finger-prick blood sample you can take yourself in the comfort of your own home. Or you can choose to have you sample taken by a member of our team.
Whether you have been recently vaccinated or caught Covid-19 naturally, this IgG test will confirm whether your immune system has developed neutralising IgG antibodies and give you a quantitative measure of your body's response (between levels of 0 - 80,000 AU/ml).
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 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.

Biomarker Profiles
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 so this test will tell you how well your body has responded to the vaccine.
Immunoglobulin G (IgG) is the most common type of antibody in your blood and other body fluids. These antibodies protect you form infection by "remembering" which infections you've been exposed to in the past. If the infection is seen again, your body knows how to attack it.
