A simple approach to screen rare donors in Brazil

Abstract

Providing blood units for patients with an antibody to a high-prevalence antigen or with multiple common antibodies is a constant challenge to the blood banks. Finding a compatible donor requires extensive screening, which incurs a large amount of investment. In this article, we share our experience of organizing a rare donor inventory with limited resources, we include the strategy used for finding rare donors, and we share the difficulties found during the implementation of the approach and the results obtained.
