SARS-CoV-2 Antibody, IgG, Spike

Your Holistic Doc

Qualitative and semi-quantitative detection of antibodies to SARS-CoV-2 spike protein receptor binding domain (RBD)

Although Insurance will not cover this test, Your Holistic Doc Now offers it to you through our WELLESS LABS for $150.00. I use this test to determine if people NOT vaccinated have been infected with SARS-COV-2.

    Aids in identifying individuals with an adaptive immune response to SARS-CoV-2, indicating recent or prior infection. Serum or plasma samples from the very early (pre-seroconversion) phase can yield negative findings. Therefore, this test cannot be used to diagnose an acute infection.

    At this time it is unknown how long antibodies persist following infection and if the presence of antibodies confers protective immunity.

    The performance of this test has not been established in individuals that have received a COVID-19 vaccine.

    The clinical significance of a positive or negative antibody result following COVID-19 vaccination has not been established and the result from this test should not be interpreted as an indication or degree of protection from infection after vaccination.

    Be aware that vaccines trigger antibodies to specific viral protein targets. For example, currently authorized COVID-19 mRNA vaccines induce antibodies to the spike protein and not to nucleocapsid proteins that are likely detected only after natural infections. Therefore, COVID-19 vaccinated people who have not had previous natural infection will receive a negative antibody test result if the antibody test does not detect the antibodies induced by the COVID-19 vaccine.

    FDA Actions

    The FDA will continue to monitor the use of authorized SARS-CoV-2 antibody tests for purposes other than identifying people with an immune response to SARS-CoV-2 from a recent or prior infection.

    WHAT THIS MEANS is that the FDA does not currently believe that this test can tell you whether the vaccine produced COVID antibodies. 

    A negative test result does not rule out the possibility of an infection with SARS-CoV-2.  It has also been reported that certain patients with confirmed infection do not develop SARS-CoV-2 antibodies. Furthermore, waning of antibody titers has been reported in some individuals within a range of months after infection, a feature which has also been reported for other coronaviruses.
