The federal Americans with Disabilities Act (ADA) also allows employers to require physical exams but imposes slightly different requirements.
Applicants. With respect to job applicants, no exam may be given until after a conditional offer of employment has been made, and then only if the exam is required of all prospective employees for the job. An employer may ask a prospective employee whether he or she can perform job-related functions.
Employees. Employees may be required to submit to medical exams that are job-related and consistent with business necessity.
Unlike the Louisiana law, which covers employers with 20 or more employees, the ADA covers employers with 15 or more employees. Louisiana employers subject to the ADA may require physical exams for applicants after extending a conditional offer of employment.
Additional information on the ADA's requirements is available.
