House Bill 466 amends Tennessee Code Annotated, Title 68, Chapter 29, Part 1, by introducing a new requirement 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 also specifies that the laboratory is not required to have the supervisor physically present on the premises.

The act 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. This change aims to enhance the operational standards of medical laboratories in Tennessee.
