Test to determine if you have detectable antibodies to the SARS CoV-2 Virus. Results determined through blood analysis with results delivered in 2-3 days.
Antibodies are a protective protein produced by the immune system in response to the presence of a foreign substance, called an antigen. As antibodies circulate, they attack and neutralize antigens that are identical to the one that triggered the immune response. Antibodies can be produced even if a person has few or no symptoms during the infection.
The test detects antibodies against the nucleocapsid (N) protein of the SARS-CoV-2 virus, and spike (S) protein which are elicited antibodies of the virus particle.
At this time, it is not known if the presence of antibodies to COVID-19 means you are immune to the virus and protected from re-infection. Importantly, it is not known how long antibody response to COVID-19 virus lasts.
If you suspect that you previously had COVID-19, even if you never showed symptoms or signs of illness, you may wish to consider the Vector Health Antibodies test to assess recent or prior infection. Antibody responses to the virus take time to develop and vary between individuals. For most accurate results (results with highest sensitivity) it is recommended the antibody test is conducted 3-4 weeks post-onset of symptoms or post-exposure. However, based on current studies, antibodies to COVID-19 virus can be detected up to 4 months post-exposure.
Levels between 2.5 and 20 do not represent ‘protection level’. Numbers are based on personal characteristics and are a point in time measure.
The Vector Health Antibodies test is not to be used for diagnosis of an active COVID-19 infection. A molecular test is used to diagnose infection.
If your results still show an elevated S-Protein Reactivity Index months after COVID-19 vaccination, it is an indication that you have successfully generated an immune response through vaccination and S-Protein specific antibodies have been created to possibly help protect you from severe symptoms and outcomes from subsequent exposure to COVID-19. However, it is always recommended to continue to follow Public Health guidelines with regards to hand washing, mask wearing and physical distancing.
A negative reactivity index COVID-19 antibody test means that antibodies to SARS-CoV-2 were not detected in your blood sample.
This could mean that:
Some studies indicate that a small percentage of people infected with SARS-CoV-2 do not have detectible antibodies (< 4%). Immunocompromised individuals may have low antibody responses to SARS-CoV-2
A positive reactivity index COVID-19 antibody test means that antibodies were detected in your blood sample.
This typically indicates that:
A single 7-8ml vial of blood is drawn from the patients arm.
The collected sample is spun down and sent to our lab for analysis.
