Naïve sensitivity of diagnostic tests estimated in those who had blood culture positive for <i>O</i>. <i>tsutsugamushi</i>, had a combination of PCR assays positive or had an eschar.

Data are sensitivity (n positive). * IFA IgM was defined as positive in those with either admission IFA IgM titre of ≥1: 12,800 or at least a four-fold rise in convalescence IFA IgM titre compared to the admission IFA IgM titre. ** A combination of PCR assays was defined as positive when at least two out of the three PCR assays (56kDa PCR assay, 47kDa-based real-time PCR assay and groEL-based real-time PCR assays) were positive. Naïve sensitivity of diagnostic tests estimated in those who had blood culture positive for O. tsutsugamushi, had a combination of PCR assays positive or had an eschar.本数据集收录的指标为诊断敏感性（阳性例数记为n）。 * 间接免疫荧光试验（Indirect Fluorescent Antibody, IFA）IgM抗体检测的阳性判定标准为：受试者入院时的IFA IgM抗体滴度≥1:12800，或恢复期IFA IgM抗体滴度较入院时至少升高4倍。 ** 联合聚合酶链反应（Polymerase Chain Reaction, PCR）检测的阳性判定标准为：三项PCR检测（56kDa PCR检测、基于47kDa的实时荧光定量PCR检测、基于groEL的实时荧光定量PCR检测）中至少两项结果呈阳性。 诊断试验的未校正敏感性通过以下三类受试者估算：血培养检出恙虫病东方体（Orientia tsutsugamushi）阳性者、联合PCR检测阳性者，或存在焦痂者。
