The quantitative formalin ethyl acetate concentration technique (QFEC) was compared to agar plate culture (APC) for the detection of Strongyloides stercoralis larvae. QFEC could substitute for APC only when the parasite load was higher than 50 larvae per g of stool. This study serves as a good reminder to those conducting stool exams about the sensitivity and specificity limitations of both techniques.
将定量福尔马林乙酸乙酯浓缩技术(QFEC)与琼脂平板培养法(APC)用于检测粪类圆线虫幼虫进行了比较。只有当寄生虫负荷高于每克粪便50条幼虫时,QFEC才能替代APC。这项研究很好地提醒了那些进行粪便检查的人,这两种技术在敏感性和特异性方面都存在局限性。
