A member asked:
Will the spike protein antibody test show if you developed antibodies to a covid-19 vaccination?

Current antibody tests for covid only test for the spike protein. Other antibody tests,not currently available,may test positive for other components even if the spike protein test is negative.

Yes. Antibody to spike protein only is seen in vaccination. Natural Covid-19 infection results in antibodies to other capsid proteins and spike protein. Lab tests can differentiate the immune response from vaccination from that due to viral infection.

I had a SARS-CoV2 Semi-Quant IgG Ab test result of 542.0 Au/mL. I was told this showed vaccine induced antibodies to the spike protein. Was that not true? Does it mean I had a previous covid infection?
