House Bill 466 amends Tennessee Code Annotated, Title 68, 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 performed. However, it specifies that the supervisor is not required to be physically present on the laboratory premises.

Additionally, the bill's effective date has been modified. Originally set to take effect on July 1, 2025, it has been changed to take effect immediately upon becoming law. This adjustment emphasizes the urgency of the bill's provisions for ensuring proper supervision in medical laboratories.
