State legislation addresses genetic discrimination in both employment and health insurance. Thirty-one states have passed laws that address genetic discrimination in employment. Approximately thirteen states prohibit employers from requiring applicants to undergo genetic testing as a condition of employment. Some states have more limited restrictions. Florida prohibits only the screening of applicants for the sickle-cell trait. Wisconsin requires employers to obtain written and informed consent from applicants prior to administering genetic tests, but does not preclude their utilization altogether. Some states establish exceptions that permit genetic testing that is job-related or that is conducted, with the employee's written and informed consent, for the purpose of investigating Worker's Compensation claims or to protect the employee's health by testing for potential work-related medical problems.
