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.
背景
本研究旨在评估巴西南里奥格兰德州血液供者中查加斯病的血清流行率。
方法
本研究基于南里奥格兰德州佩洛塔斯血液中心登记的数据，于 2010 年至 2019 年进行。
结果
共检测了 106320 份血样，因抗 T. cruzi 抗体阳性反应或结果不确定而报废的血袋率为 0.27%（283 袋）。
结论
使用能够安全识别出查加斯病血清学阳性供者的方法对于确保输血安全至关重要。
