Whenever the Department or a local health authority has reasonable grounds to suspect a person of being infected with an organism causing a sexually transmitted disease, tuberculosis or other communicable disease, or of being a carrier, but lacks confirmatory medical or laboratory evidence, the Department or the local health authority may require the person to undergo a medical examination and any other approved diagnostic procedure to determine whether or not the person is infected or is a carrier. If the local health authority involved is not an LMRO, the local health authority shall consult with and receive approval from the Department prior to requiring any medical examination or other approved diagnostic procedure.
