Review your results with a network of physicians (PWNHealth), Request the test either in-person or via a telehealth service. The test is not able to differentiate whether the antibodies produced were in response to the vaccine or to a prior infection. These are called memory B cells. It is possible to receive vaccines and not develop antibodies, says Dr. Ramirez. 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.

At the moment, scientists dont know how antibody levels relate to your overall protection from COVID-19. Ann Clin Lab Sci. An official website of the United States government. 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. 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. Visit a Labcorp patient service center or your doctor's office to have the blood work drawn. Many research studies (including the clinical trials for the COVID-19 vaccine), have used these tests to look specifically at neutralizing antibodies, since these antibodies can block (neutralize) virus particles preventing them from binding to and infecting your cells. Some tests look for antibodies to both the spike protein and the nucleocapsid protein to distinguish between vaccination and infection. After a single vaccine injection, the median titer of specific antibodies in individuals with previous coronavirus disease 2019 was 30.527 U/ml (interquartile range [IQR]: 19.992-39.288) and in subjects with previous SARS-CoV-2 asymptomatic infection was 19.367.5 U/ml (IQR: 14.688-31.353) (p = .032).
