• I'm part of a group of people whose blood is used to evaluate a couple of antibody tests, having tested positive via nasal swab 6 weeks ago and getting comparatively mild symptoms. Results are quite interesting and confusing so far. I've developed antibodies but my mate hasn't, for example. My antibodies took 3 weeks from when symptoms started to be detectable, others have had lots & lots after only 7 days.

  • Are other viruses like that?

    Sounds pretty complicated to make a test if the results vary so much in response / time to response.

  • There's been an interesting paper related to Lyme disease that shows some people mount a very strong B cell response and rapidly clear the disease where others whose response is slower and not strong will have longer duration of illness/symptoms even after treatment. They're now looking at using the stronger Borrelia specific antibody cells as a potential therapeutic for those whose bodies can't produce them themselves.

    May be the same rationale with Covid cases
