The U.S. Equal Employment Opportunity Commission (EEOC) has announced that COVID-19 antibody tests cannot be required before employees are permitted to return to the workplace.  Since an antibody test constitutes a medical examination under the Americans with Disabilities Act (ADA), it is only permitted when it is “job related and consistent with a business necessity.”   Relying on the Centers for Disease Control and Prevention’s (CDC) guidance that antibody tests “should not be used to make decisions about returning persons to the workplace[,]” the EEOC concluded that the testing is neither.  As a result, mandatory antibody testing is prohibited by the ADA.
