The purpose of this legislation, known as the "BLOOD Centers Act," is to create a faster approval process for certain applications related to blood donation centers. Specifically, it aims to streamline the process for blood centers that want to add new equipment for collecting blood, making it easier and quicker for them to operate and expand their services. Key provisions of the act include the establishment of an expedited process for approving supplemental applications from blood centers. This process must be set up within 180 days of the law being enacted.
