We evaluated a commercially available immunochromatographic dipstick test to detect Trypanosoma cruzi infection in 366 human serum samples with known serological results from Argentina, Ecuador, Mexico, and Venezuela. One hundred forty-nine of 366 (40.7%) and 171/366 (46.7%) samples tested positive by dipstick and serology, respectively. Dipstick sensitivity was calculated to be 84.8% (range between countries, 77.5 to 95%), and specificity was 97.9% (95.9 to 100%).
我们评估了一种市售的免疫层析检测试剂盒,用于检测来自阿根廷、厄瓜多尔、墨西哥和委内瑞拉的 366 个人类血清样本中的克氏锥虫感染。分别有 149/366(40.7%)和 171/366(46.7%)的样本通过免疫层析和血清学检测呈阳性。免疫层析的灵敏度计算为 84.8%(各国之间的范围为 77.5%至 95%),特异性为 97.9%(95.9%至 100%)。
