One tool many are banking on is the antibody test. Rachel Horton, a lecturer in law at the University of Reading, told CNN that UK employees who felt they had faced discrimination due to their antibody status would have limited legal protections, as antibody status is not currently considered a protected characteristic under anti-discrimination law. Horton said an employer could in theory justify requiring someone to disclose their antibody status if they could prove it was necessary for health and safety. False reassuranceWhile many commercial manufacturers are rushing to produce antibody tests, at least some on the market are fraudulent or unreliable, producing false positive results that could lead people to mistakenly believe they have already been infected. Paul Hunter, a professor of health protection at England's University of East Anglia, also raised concerns about access to antibody tests.
