Sensitivity of DENV NS1 antigen compared to RT-PCR and/or virus isolation in acute and positive rate of the convalescent specimens.

Sensitivity of dengue NS1 antigen in primary and secondary DENV infection status.*Comparison to RT-PCR DENV positive samples,¶Comparison to IgM seroconversion¶Number of samples tested differed to total number due to either duplicates for RDTs, invalid test or equivocal result.Acute is days post onset of fever (DPO) of 0–5 days, convalescent is DPO = 6–14.Primary = 1 DENV infection, Secondary ≥2 DENV infections.CI95 = 95% confidence interval.Sensitivity of DENV NS1 antigen compared to RT-PCR and/or virus isolation in acute and positive rate of the convalescent specimens.

登革病毒NS1抗原（dengue NS1 antigen）在登革病毒（DENV）原发与继发感染状态下的检测灵敏度。
* 与登革病毒RT-PCR（逆转录聚合酶链反应）阳性样本的对比
¶ 与IgM（免疫球蛋白M）血清阳转的对比
¶ 因快速诊断试纸（RDT）存在重复检测、结果无效或可疑结果的情况，实际检测样本数与总样本数存在差异。
急性期为发热发病后0~5天（DPO，即发病后天数），恢复期为发病后6~14天。
原发感染为1次登革病毒感染，继发感染为≥2次登革病毒感染。
CI95即95%置信区间（95% confidence interval）。
登革病毒NS1抗原的检测灵敏度以急性期样本对比RT-PCR和/或病毒分离结果、恢复期样本对比阳性检出率进行评估。
