We evaluated the Binax NOW Streptococcus pneumoniae urinary antigen assay by testing 210 healthy children aged 2--60 months living in urban slums of Quito, Ecuador. Healthy children with nasopharyngeal carriage of S. pneumoniae were significantly more likely to have positive urinary antigen test results than were children who were not carriers (30 of 138 vs. 3 of 71 children; chi2=10.8; P<.001). The rate of nasopharyngeal carriage of S. pneumoniae decreased with increasing age; the lowest rates were found in children with the worst nutritional status.
我们对Binax NOW肺炎链球菌尿抗原检测法进行了评估，检测了居住在厄瓜多尔基多市城市贫民窟的210名2至60个月大的健康儿童。肺炎链球菌鼻咽部带菌的健康儿童尿抗原检测结果呈阳性的可能性显著高于非带菌儿童（138名儿童中有30名，71名儿童中有3名；卡方检验=10.8；P<0.001）。肺炎链球菌的鼻咽部带菌率随年龄增长而降低；营养状况最差的儿童带菌率最低。
