There are many legitimate reasons for employers to give preemployment physical exams to applicants and periodic exams to current employees--for example, preemployment drug testing or exams to ensure that a job candidate is physically capable of performing the required tasks of a particular job. Employers must comply with state and federal laws, such as the Americans with Disabilities Act (ADA), which restrict the timing and scope of certain medical exams. The Family and Medical Leave Act (FMLA) also requires employers to comply with its regulations when medical information is required to verify the need for a leave of absence. Laws such as the Genetic Information Nondiscrimination Act (GINA) also affect an employer's request for medical information.
