Elecsys Syphilis Signal-to-Cutoff
收藏资源简介：
Supplementary file 1: Data for 19,368 syphilis screening tests on 15,764 unique patients using the Roche Diagnostics Elecsys Syphilis assay. All laboratory data involve analysis on plasma or serum. Specific data fields include: unique patient identification number (deidentified), whether result was first or only syphilis screening test performed for the specific patient within the retrospective timeframe or a repeat test (with days after initial test recorded), age in years, sex (as recorded in the electronic medical record), clinical location/unit at time of testing (emergency department, infectious disease clinic, obstetrics, inpatient, or outpatient clinic other than infectious diseases or obstetrics), syphilis screening result (negative or positive), and S/CO value for the syphilis screening. Supplementary file 2: Data for 355 positive syphilis screening tests on 270 unique patients using the Roche Diagnostics Elecsys Syphilis assay. All laboratory data involve analysis on plasma or serum. Specific data fields include: unique patient identification number (deidentified), whether result was first or only syphilis screening test performed for the specific patient within the retrospective timeframe or a repeat test, age in years, sex (as recorded in the electronic medical record), clinical location/unit at the time of syphilis testing (emergency department, infectious disease clinic, obstetrics, inpatient, or outpatient), S/CO value, results of subsequent testing in the reverse algorithm cascade (classified into the following categories: RPR reactive with specific titer noted, RPR and TP-PA non-reactive, RPR non-reactive / TP-PA inconclusive, and RPR non-reactive / TP-PA reactive), specific category (including RPR reactive results broken down into 1:1 to 1:8 and 1:16 or higher subgroups), and clinical notes.
补充文件1：针对15764名独特患者开展的19368项梅毒筛查检测数据，采用罗氏诊断（Roche Diagnostics）Elecsys梅毒检测试剂盒完成。所有实验室数据均针对血浆或血清样本开展分析。具体数据字段包括：去标识化的唯一患者识别编号、本次检测为该回顾性时间范围内患者首次/仅有的梅毒筛查检测，还是复检（并记录首次检测后的天数）、患者年龄（岁）、电子病历中记录的性别、检测时的临床科室/单元（急诊科、感染病科门诊、产科、住院部，或除感染病科与产科外的普通门诊）、梅毒筛查结果（阴性或阳性），以及梅毒筛查的S/CO值。补充文件2：针对270名独特患者开展的355项阳性梅毒筛查检测数据，采用罗氏诊断（Roche Diagnostics）Elecsys梅毒检测试剂盒完成。所有实验室数据均针对血浆或血清样本开展分析。具体数据字段包括：去标识化的唯一患者识别编号、本次检测为该回顾性时间范围内患者首次/仅有的梅毒筛查检测，还是复检、患者年龄（岁）、电子病历中记录的性别、梅毒检测时的临床科室/单元（急诊科、感染病科门诊、产科、住院部或普通门诊）、S/CO值、后续采用逆向检测算法开展的联检结果（分为以下类别：快速血浆反应素试验（RPR）阳性并记录具体滴度、RPR与梅毒螺旋体颗粒凝集试验（TP-PA）均为阴性、RPR阴性/TP-PA结果无定论、RPR阴性/TP-PA阳性）、具体分类（含将RPR阳性结果细分为1:1至1:8、1:16及更高滴度亚组），以及临床备注。
