Background on Antibody Testing for SARS-CoV-2 Infection: In most individuals, exposure to the virus, or receipt of a COVID-19 vaccine, will result in the production of detectable antibodies in the serum within 2 weeks. Morales-Nez JJ, Garca-Chagolln M, Muoz-Valle JF, Daz-Prez SA, Torres-Hernndez PC, Rodrguez-Reyes SC, Santoscoy-Ascencio G, Sierra Garca de Quevedo JJ, Hernndez-Bello J. J Inflamm Res. 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). Seropositivity against the receptor-binding domain (RBD) of the SARS-CoV-2 spike protein was measured from the participants 4 weeks after the second dose of vaccine using the electrochemiluminescence (ECLIA) method. You send the blood sample to a lab to be analysed. The site is secure. Forgacs D, Jang H, Abreu RB, Hanley HB, Gattiker JL, Jefferson AM, Ross TM.
