2. A negative antibody test doesn’t necessarily mean you don’t have antibodies and it certainly doesn't mean you didn't have COVID. First of all, the accuracy of C19 antibody tests has been questioned by the CDC and others. Some C19 antibody tests have a high false negative rate.
3. For instance, some of the tests authorized by the FDA have a sensitivity rate under 90% - which means if 100 ppl are tested, 10 or more will be told they don’t have antibodies when they actually do. And that’s the rate reported by the manufacturer, not the rate in actual use.
