COVID-19 Antibody Test Selection Guide Considerations Negative antibody results in persons collected earlier than 21 days after symptom onset may be negative due to the kinetics of seroconversion, specifically, some patients will not have measurable antibody until more than 21 days after symptom onset. They prompt other immune system cells to eliminate foreign substances. Currently, Be aware that vaccines trigger antibodies to specific viral protein targets. T cell responses are much harder to measure than antibodies. A positive antibody test result can help identify someone who has had COVID-19 in the past or has been vaccinated against COVID-19.

Theres also a difference between having no antibodies and having some antibodies. There isnt enough data on immunocompromised populations yet to determine how they may react to the vaccine, but experts still believe youll get some immunity which is far better than none if you are immunocompromised. Although there are different types of these antibody tests, researchers traditionally inject a blood sample with viral particles (which may be made from other virus backbones but with the SARS-CoV-2 spike protein expressed on their surfaces).

The study was powered for non-inferiority. After a coronavirus infection or a vaccination, the body produces antibodies against the virus' spike protein, which SARS-CoV-2 uses to dock onto the cells and penetrate them. On the other hand, the vaccines currently authorized for use in the United States only trigger antibodies against spike protein, so an antibody test after you get the vaccine should only detect antibodies to that spike protein, not to the nucleocapsid protein.
