To prohibit the use of Federal funds to implement, administer, or enforce a final rule of the Food and Drug Administration relating to "Medical Devices; Laboratory Developed Tests", and for other purposes.

HR 1463 prohibits the use of federal funds to implement, administer, or enforce a specific FDA rule about medical devices known as "laboratory developed tests" (LDTs), published in the Federal Register on May 6, 2024 (89 Fed. Reg. 37286). The bill directly affects the Food and Drug Administration (FDA), preventing it from using taxpayer money to carry out this regulation. Its key mechanism is a straightforward funding ban on the specified rule and any substantially similar future rule. This is a procedural restriction focused solely on blocking financial support for the FDA's LDT regulatory approach.
