House Bill 466 amends Tennessee Code Annotated, Title 68, by introducing a new requirement for medical laboratories regarding the availability of a medical laboratory supervisor. The bill mandates that each medical laboratory must have a 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.

The bill is set to take effect on July 1, 2025, emphasizing the importance of having supervisory oversight during testing while allowing flexibility in the supervisor's location. This change aims to enhance the operational standards of medical laboratories in Tennessee.
