One Blood sent me a letter concerning my blood donation. The antibody test was “postive” and therefore I have been exposed to Coronavirus in the past.
Well.... maybe, maybe not. According to current CDC guidelines, people such as myself who have been vaccinated may show positive on some test. One blood will have to update their form letter now that people who both donate blood and are vaccinated exist.

Currently available antibody tests for SARS-CoV-2 assess IgM and/or IgG to one of two viral proteins: spike or nucleocapsid. Because both the Pfizer-BioNTech and Moderna COVID-19 vaccines contain mRNA that encodes the spike protein, a positive test for spike protein IgM/IgG could indicate either prior infection or vaccination. To evaluate for evidence of prior infection in an individual with a history of mRNA COVID-19 vaccination, a testexternal icon specifically evaluating IgM/IgG to the nucleocapsid protein should be used. Antibody testing is not currently recommended to assess for immunity to COVID-19 following mRNA COVID-19 vaccination or to assess the need for vaccination in an unvaccinated person
