With the availability of antibody tests for the detection of antibodies against COVID-19, employers are asking themselves whether they should use such tests as part of their company’s pandemic management. JDMT is of the opinion that currently, COVID-19 antibody tests are not suitable for use in the workplace. There is currently insufficient evidence that antibodies to COVID-19 also mean immunity to COVID-19. And only a small percentage of the population has presumably been infected with COVID-19 so far. Finally, it must also be kept in mind that careless behaviour by COVID-19 antibody carriers could damage the discipline of other employees to strictly observe the rules of hygiene.
