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. [Antibody Response After Two Doses of Inactivated SARS-CoV-2 Vaccine in Healthcare Workers with and without Previous COVID-19 Infection: A Prospective Observational Study]. 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). This can give you peace of mind, and can now be done from the safety and comfort of home.

If people dont have high enough levels, they can receive booster vaccines for hepatitis B or even the entire vaccine series. Thats because different serology tests detect antibodies to different parts of the virus. A vaccinated person should not be alarmed or worried if they receive a negative antibody test result because this test does not detect antibodies from the Pfizer, Moderna and Johnson & Johnsons Janssen COVID-19 vaccines, which were developed against the spike protein of the virus, says Fernando Martinez, M.D., medical director of Laboratory Medicine.

This change does not impact previously reported results; it just increases the numerical values above 2500 U/mL that we are able to report. The mRNA vaccine induces a strong antibody response to SARS-CoV-2 and five VOCs at 1 week post-vaccination that decreases thereafter. It would require a physician who understands the antibody testing well enough and also knows the individuals personal medical history, including medication and vaccination timing and history, so that they could have an informed discussion with the person and make an individual management decision, says Dr. Ramirez. Timing is also crucial, as patients who have not been infected long enough to develop antibodies would test negative.
