I was positive for COVID and have no antibodies. Don’t assume you didn’t have it if you don’t have antibodies.

- briefcomment 6y agoIt is possible to overcome the virus without antibodies. I forgot the name for the process, but I'll try to track it down.

- jaboutboul 6y agoInterested. Please do.

- foobiekr 6y agoI think what you are referring to is that it is apparently possible, in some patients, for the innate immune system to stop the infection before adaptive immunity kicks in, which would leave you both without antibodies and subject to reinfection at a later point. This can also reduce the adaptive response level.
- three_seagrass 6y agoYep. Cytotoxic T-Cells can wipe out a viral infection, especially with the help of interferons, before the B-Cells can develop an effective antibody response. Keep in mind that viruses are incredibly tiny and have small antigenic surface areas compared to bacteria. It also means you are likely to get infected again.
- jansan 6y agoHow long after the illness did you have the antibody test taken? My wife was tested positive in April, had all the symptoms, so it is almost 100% sure that she actually had COVID-19. THe antibody test two weeks after the symptoms were gone was negative. The second antibody test a few days later was ambigous. She is planning to take a third antibody test next week.
