What can I expect from this COVID-19 Vaccine and Immune Response – “Quantitative” Antibody Blood Test?
One in 100 people does not produce antibodies against their vaccine and not developing antibodies against the virus has been linked to increased hospitalization and serious illness. Recent research has shown that the early immune response in people who have been vaccinated for COVID-19 can predict the level of protection they will have against the virus over time and potentially your body’s efficacy to combat viral variants such as the delta variant currently responsible for the majority of new Covid-19 cases in the UK. Some scientists have suggested that a test for antibody status may now become the norm when people are admitted to a hospital with severe Covid-19.
This new test (January 2021) “was designed to aid in evaluating the immune status of individuals with a quantitative measurement of IgG antibodies against the spike receptor binding domain (RBD) of SARS-CoV-2.”
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 a blood sample taken in-store.
Whether you have been recently vaccinated or caught Covid-19 naturally, this IgG test will confirm whether your immune system has developed neutralizing 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 infection to confirm whether the illness you had was Covid-19 or something else.
