If a medical laboratory performs mycobacterial drug susceptibility tests of cultures that are identified as <em>M. tuberculosis</em> and that have not been referred to the Maryland Laboratories Administration for this determination, the individual in charge of the laboratory must report the test results to the Commissioner. Unless a different time is set by the Commissioner or by State law, the report must be made within 48 hours of obtaining the test results. City Code, 1976/83, art. 11, §206(f) Ord. 99-548
