Public Health - As enacted, requires a medical laboratory supervisor to be readily available for consultations during all hours when tests are performed; prohibits a medical laboratory supervisor from being required to be on laboratory premises. - Amends TCA Title 68.

SB 1385 requires Tennessee medical laboratories to ensure a medical laboratory supervisor is readily available for consultations during all hours tests are performed, but prohibits labs from mandating supervisors be physically present on-site. This directly affects all medical laboratories operating under Tennessee Code Annotated Title 68. The key provision replaces the previous requirement for on-premises supervision with a remote availability standard, effective July 1, 2025. The law aims to maintain oversight flexibility while ensuring timely expert consultation during testing operations.
