I was just made aware of this study that may be of interest for people who suspect they may have had a COVID infection.

- COVID-19 Antibody Detection Study https://joinastudy.niehs.nih.gov/studies/antibody-detection/index.htm

“ This year-long study will test adult volunteers for antibodies in their blood that indicate exposure to SARS-CoV-2, the virus that causes COVID-19. Researchers hope to learn more about disease symptoms and how many antibodies stay in a person’s blood over the course of a year. This information will help inform public health efforts in the future.”
