Our Purpose
Why should you get an antibody test for COVID-19?
Post-Vaccination:
Taking a Neutralizing Antibody Test after a month after your second vaccine dose (Pfizer or Moderna), or one month after the Johnson & Johnson single dose vaccine, to check whether your body produced an immune response containing neutralizing antibodies, against the COVID-19 vaccine. Experts do not know the length of time our immunity last post-vaccination and when or how frequent vaccine booster shots are required.

General Curiosity and Healthy Confidence:
To check your COVID-19 immune status before or after vaccination, or if you're just curious about your health. The Neutralizing Antibody Test is available for front line workers, healthcare workers, educators, and the general public. Antibodies are detectable approximately 1 to 2 weeks after the onset of infection (Guo, March 2020; Zhao, March 2020; Compeer, August 2020), with IgA, IgM and IgG rising in concert (CDC, August 2020). Levels of IgM and IgA begin to fall starting 2 to 3 weeks post-infection while IgG persists for longer. Exactly how long these antibodies stay detectable and in what populations is not fully known.
The Genscript cPass test
This test will help to determine whether you have functional neutralizing antibodies, qualitatively as well as semi-quantitatively, using the only FDA EUA test for neutralizing antibodies against the SARS-CoV-2 virus. It is possible that other IgG/IgM antibody tests do not provide results on the functional or neutralizing aspect of the antibodies (only providing the total antibody fraction).
SARS-CoV-2 has a biological key, called a spike protein, that allows it to bind to receptors on the cell membrane and unlock the door to human cells. Once inside of cells, the virus replicates and causes infection such as COVID-19. The immune system produces neutralizing antibodies which bind to the viral spike protein and block its ability to function as a key. Neutralized SARS-CoV-2 can no longer enter human cells or cause infection.
