House Bill 466, sponsored by Helton-Haynes, amends Tennessee Code Annotated, Title 68, by adding a new section to establish requirements for medical laboratories. The bill mandates that each medical laboratory must have a medical laboratory supervisor available for consultations during all hours when tests are conducted. However, it specifies that the supervisor is not required to be physically present on the laboratory premises.

This legislation is set to take effect on July 1, 2025, emphasizing the importance of having supervisory oversight in medical laboratories while allowing for flexibility in the supervisor's location.
