BACKGROUND
The World Health Organization recommends a market-ready, urine-based point-of-care diagnostic test for circulating cathodic antigens (CCA) to determine the prevalence of S. mansoni. This study evaluated the performance of the URINE CCA (SCHISTO) ECO TESTE® (POC-ECO), which is currently available in Brazil.
METHODS
Residents from eight sites with different prevalence estimates provided one urine sample for POC-ECO and one stool sample for Kato-Katz (KK) and Helmintex® (HTX) testing as an egg-detecting reference for infection status.
RESULTS
None of the study sites had significantly higher POC-ECO accuracy than KK.
CONCLUSIONS
POC-ECO is not currently recommended in Brazilian schistosomiasis elimination programs.
背景
世界卫生组织建议使用市售的、基于尿液的即时检测诊断试验来检测循环阴转阳离子（CCA），以确定曼氏血吸虫的流行情况。本研究评估了目前在巴西可用的 URINE CCA（SCHISTO）ECO TESTE®（POC-ECO）的性能。
方法
来自八个不同流行率预估地点的居民提供一份尿液样本进行 POC-ECO 检测，以及一份粪便样本进行加藤厚涂片（KK）和 Helmintex®（HTX）检测，作为感染状况的虫卵检测参考。
结果
没有一个研究地点的 POC-ECO 检测准确性明显高于 KK。
结论
POC-ECO 目前不推荐用于巴西血吸虫病消除计划。
