If suitable accuracy can be established, the benefits of these antibody tests include establishing when healthcare workers are immune, helping to inform decisions about the lifting of lockdowns, and allowing the population to return to work.25, The WHO message “test, test, test”1 is important from a population perspective; low sensitivity can be accounted for when assessing burden of disease.
