Publishing negative seroprevalence studies not only helps to have more accurate seroprevalence estimates but also allows calculating the specificity of the diagnostic tests used. We performed a population-based Trypanosoma cruzi seroprevalence survey in a community in central Mexico.
We surveyed 204 women and children and collected blood by finger prick. We performed rapid tests (Stat-Pak, Chembio, Inc., Medford, New York) and recombinant Chagas ELISA tests v3.0 (Wiener, Rosario, Argentina). All rapid tests and all ELISA tests were negative.
The rapid test had 100 % of specificity compared to the ELISA.
发表血清阳性率阴性研究不仅有助于获得更准确的血清阳性率估计值,还能计算所用诊断测试的特异性。我们在墨西哥中部的一个社区进行了一项基于人群的克氏锥虫血清阳性率调查。
我们调查了204名妇女和儿童,通过手指采血。我们进行了快速检测(Stat-Pak,Chembio公司,纽约州梅德福)和重组查加斯酶联免疫吸附测定v3.0检测(Wiener,阿根廷罗萨里奥)。所有快速检测和所有酶联免疫吸附测定检测均为阴性。
与酶联免疫吸附测定相比,快速检测的特异性为100%。
