Every exposure is like a booster shot. You don't need to get infected to get a bump in antibody production.TarponChaser said:redcrayon said:
Those CVS finger ***** tests only measure antibodies from a more recent infection. If you really want to measure antibodies, you need a blood draw. This is what an NP at CVS told me.
Well, I had covid right after Thanksgiving last year and it was extremely mild. Like 36-48 hours of fatigue and just feeling beat up. Tested for antibodies at CVS on 8/12/2021 and still had them.
I suppose it could have been a recent infection because I know I've had several exposures since but never been sick at all. So if I had it again I was asymptomatic.
So if you know you've definitely been infected, and definitively been exposed multiple times since infection, then you can't draw a definitive conclusion on how long antibody remain elevated following a recovery.
