The Equal Employment Opportunity Commission (EEOC) has stated the Americans with Disabilities Act (ADA) prohibits mandatory antibody testing before allowing employees to return to the worksite.  However, employers may require a doctor’s note certifying fitness for duty. 

An antibody test constitutes a medical examination under the ADA. In light of CDC’s Interim Guidelines that antibody test results “should not be used to make decisions about returning persons to the workplace,” an antibody test at this time does not meet the ADA’s “job related and consistent with business necessity” standard for medical examinations or inquiries for current employees. Therefore, requiring antibody testing before allowing employees to re-enter the workplace is not allowed under the ADA. 

Please note that an antibody test is different from a test to determine if someone has an active case of COVID-19 (i.e., a viral test).  The EEOC has already stated that COVID-19 viral tests are permissible under the ADA.

The ADA requires that any mandatory medical test of employees be “job related and consistent with business necessity.” Applying this standard to the current circumstances of the COVID-19 pandemic, employers may take steps to determine if employees entering the workplace have COVID-19 because an individual with the virus will pose a direct threat to the health of others. Therefore, an employer may choose to administer COVID-19 testing to employees before they enter the workplace to determine if they have the virus.
