The James J. Peters VA Medical Center requires courier services for critical transplant-related diagnostics and logistics throughout all phases of patient care. The services must provide both scheduled and unscheduled deliveries of blood and tissue samples promptly, securely, and in full regulatory compliance. Timely delivery is especially crucial for post-transplant patients experiencing complications to guide clinical decisions. The work will be performed for the Transplant Program at the JJP VA Medical Center. No specific budget or contract timelines are detailed in this description.
