I recently had an antibody test in an attempt to convince wife not to get the shot. I was hoping for a positive result showing natural protection. The test was negative.

From a non-scientific background the question I have is:

If I am part of the 81% who have protection from covid, would I produce antibodies to covid detectable to the antibody test I took?

I hope the question is not "too far out there."

The test was a blood test and is described as "SARS-COV-2 (COVID-19) ANTIBODY IGG."

Thank you.
