I know you can buy CV-19 "tests" over the counter in the drugstore these days to see if you have CV-19 (despite the question about numerous false positives). But what I want to know is if I've developed antibodies through natural immunity. I had COVID at the very beginning of all of this, before we knew what it was - confirmed by my doctor but not by an antibody test.
I know it would be a blood test, but is anyone aware of an OTC test that you could run on yourself? Like a reagent strip that you prick your finger and use a drop of blood? I definitely don't want to be tested by "the system", but I would like to know.
If you were infected with Sars-cov-2 and developed antibodies, those antibodies would not remain in your system past 6 months approximatively.
However the blueprint to make those antibodies remains in what is called memory cells so that if you are exposed to the virus again you can quickly whip up new antibodies specific to Sars-cov-2 and fight off the infection. So you may be immune to Sars-cov-2 but not show antibodies for it in a blood test.
That is correct. I had an antigen test done in February after having what I thought was Covid in December. I tested positive. If you wait too long the antibioties don't show up, like this person says.
Exactly. But long after the antibodies are gone (at least 17 years according to studies) you have T-cells in the bone marrow, which will be called on to produce antibodies if/when required.
Yes, I read that too! Good news for us who have had covid! I saw that those that had SARS/Cov1 17 years ago still had natural immunity, probably also to SARS/Cov2.
