I just want to know my antibody level, 2 years after my one and only J&J vaccine. Kaiser(They use Stanford Healthcare Lab) only provides a positive or negative, yet their equipment is capable of readings >2500. FDA directives are suppressing release of quantitative results to the public. I did get a lab in San Jose(Target DX) to report the semi-quantitative (>250) 1year after my J&J vaccination.
