How were you able to verify that you have developed anti-bodies?

Two nasal swabs taken when I had symptoms did not give a positive result (Abbott Labs IDNOW test), so after I recovered I requested an antibody panel and was tested for COV-2 IgG and IgM. Tests were done on Abbott Labs equipment (though the results sheet did not specify the particular assay - there are 2). My results were a high multiple of what would be considered 'positive' for both and were consistent with the timeframe of my illness.

My insurance covered the cost of all my testing as it was done in conjunction with a televisit with my GP. I hear that it is available for approximately $60 if you just pay retail for it. If you give blood at your local blood bank, many are offering the antibody test as an incentive to donate.

There’s a blood test you can pay for.

I abstained from voting for the same reason. It seems likely that people with a high enough level of antibodies will at least be at the very back of the line for vaccination.
