The State Board of Health shall make such rules and regulations pertaining to such tests as accepted medical practice shall indicate, and is authorized to make such testing mandatory if sufficient evidence exists that the public has been negligent in accepting such practice and if the Board considers it in the public interest to do so. The State Board of Health is hereby authorized to set up laboratory facilities and use existing facilities for the performance of examinations and tests for the detection of these diseases and make a reasonable charge therefor; provided, however, that no child shall be denied such laboratory work or tests because of the inability of its parents or guardian to pay therefor. Provided, further, that the State Board of Health may approve other laboratories for the performance of such tests; provided that the provisions of this section shall not apply to any infant whose parents object thereto on the grounds that such examination conflicts with their religious tenets and practices.
