We compared two collection devices, IsoCode and FTA, with whole blood for the diagnosis of malaria by PCR (n = 100). Using whole blood as the reference standard, both devices were sensitive for the detection of single-species malaria infections by PCR (> or =96%). However, the detection of mixed infections was suboptimal (IsoCode was 42% sensitive, and FTA was 63% sensitive).
我们比较了两种采集设备IsoCode和FTA,使用全血样本通过聚合酶链反应(PCR)诊断疟疾(n = 100)。以全血作为参考标准,两种设备通过PCR检测单一物种疟疾感染时均具有较高敏感性(≥96%)。然而,对于混合感染的检测效果欠佳(IsoCode敏感性为42%,FTA敏感性为63%)。
