Notwithstanding any other provision of this chapter or a regulation promulgated under this chapter, a person who collects and anonymously submits a sample of the person’s own body fluid or tissue for Human Immunodeficiency Virus (HIV) infection testing is not required to report a positive test result, and the test results are confidential. However, the person or laboratory performing the test on an anonymous sample shall report a positive HIV infection test result to the Department of Health and Environmental Control, as well as certification to the Department of Health and Environmental Control that counseling options, including community-based resources, and referrals to appropriate medical providers have been made or offered to the positive subject, but the report must not contain any information identifying the subject of the report or any information that may lead to the identification of the subject of the report.
