## Summary

Amends the Genetic Information Privacy Act. Provides that the use of genetic testing, biomarker testing, or both (rather than only genetic testing), and the information derived from testing, is confidential and privileged and may be released only to the individual tested and persons specifically authorized in writing by the individual tested to receive the information. Provides that an insurer may not seek information derived from genetic or biomarker testing (rather than only genetic testing) for use in connection with a policy of accident or health insurance (unless the individual voluntarily submits the results and the results are favorable to the individual), for nontherapeutic purposes, or for underwriting purposes. In provisions concerning the use of testing information by employers, provides that an employer may release genetic testing or biomarker testing information (rather than only genetic testing information) under specified circumstances. Limits an employer's use of genetic information, genetic testing, biomarkers, and biomarker testing (rather than only genetic information and genetic testing). In provisions concerning testing, provides that no person may disclose or be compelled to disclose the identity of any person upon whom a genetic test or biomarker test (rather than only genetic test) is performed or the results of a genetic test or biomarker test (rather than only a genetic test) in a manner that permits identification of the subject of the test, except to the persons specified in the Act. Limits the concurrent exercise of home rule powers. Defines "biomarker" and "biomarker testing". Makes other and conforming changes.
