Cleveland Clinic does not have any antibody test ready or anticipate one soon, ProMedica in Ohio is doing antibody tests.
You have it backwards. In general, PCR testing is more accurate than antibody testing. Antibody tests don’t tell you if you have the infection, but only if you may have had it in the past. And if doing an IgG test, it can take your body up to 4-6 weeks for your body to produce enough of the antibodies for a positive result. So a negative test within the first 4-6 weeks after the infection doesn’t rule out the possibility you had the infection. With the FDA emergency use authorization manufacturers don’t have to submit any validation data proving the sensitivity and specificity of their tests.
