Description
Summary:ABSTRACT Background: We aimed to evaluate the seroprevalence of Chagas disease among blood donors in southern Rio Grande do Sul, Brazil. Methods: The study was conducted from 2010 to 2019 based on data registered by the Hemocentro Regional de Pelotas, Rio Grande do Sul. Results: There were 106,320 blood donations, and the discard rate of blood bags, either due to positive reactions to anti-T. cruzi antibodies or inconclusive results was 0.27% (283 bags). Conclusions: The usage of methods that enable the safe identification of donors with positive serology for Chagas disease is fundamental to ensure transfusional safety.
