"How reliable are the antibody tests?

Premier Biotech, the manufacturer of the test that USC and L.A. County are using, tested blood from COVID-19-positive patients with a 90 to 95% accuracy rate. The company also tested 371 COVID-19-negative patients, with only two false positives. We also validated these tests in a small sample at a lab at Stanford University. When we do our analysis, we will also adjust for false positives and false negatives."

This 100% contradicts what Dr. Birx said in yesterday's press conference. When asked by Fox's John Roberts about these new tests showing widespread antibodies in people who were asymptomatic and didn't know they'd been infected, she immediately questioned the accuracy of antibody tests.
