The performance of a commercial immunochromatography test for rapid detection of dengue NS1 antigen present in serum or plasma of patients was evaluated against a commercial dengue NS1 antigen-capture ELISA. The rapid immunochromatography test gave an overall sensitivity of 90.4% with a specificity of 99.5%. The sensitivity was highest for serum samples from which virus was isolated (96.3%) and lowest for those from which virus was not isolated and RT-PCR was negative (76.4%). The sensitivity was significantly higher for serum samples from patients with acute primary dengue (92.3%) than those from patients with acute secondary dengue (79.1%). The positive predictive value and negative predictive value of this commercial immunochromatography test were 99.6% and 87.9% respectively.
针对一种商业登革热NS1抗原捕获酶联免疫吸附测定（ELISA），对一种用于快速检测患者血清或血浆中登革热NS1抗原的商业免疫层析试验的性能进行了评估。这种快速免疫层析试验的总体灵敏度为90.4%，特异性为99.5%。对于分离出病毒的血清样本，灵敏度最高（96.3%），而对于未分离出病毒且逆转录聚合酶链反应（RT-PCR）为阴性的样本，灵敏度最低（76.4%）。急性原发性登革热患者的血清样本灵敏度（92.3%）显著高于急性继发性登革热患者的血清样本（79.1%）。这种商业免疫层析试验的阳性预测值和阴性预测值分别为99.6%和87.9%。
