Rare Blood Banks: Challenges and Solutions in Brazil and World Wide

The growing demand for compatible blood for rare phenotypes highlights significant global and national challenges in transfusion medicine. Brazil, marked by extensive genetic diversity, faces difficulties in infrastructure, logistics, and donor identification. In contrast, countries like India, South Korea, and Austria have developed advanced genotyping techniques and robust regional registries, improving response times and transfusion safety. Despite advances such as the creation of Brazil’s national rare donor panel, gaps remain in donor recruitment and rare blood management. Adopting international best practices and expanding donor registries are essential to optimize Brazil’s rare blood supply system.
