The screening and diagnosis of dengue virus infection play a crucial role in controlling the epidemic of dengue fever, highlighting the urgent need for a highly sensitive, simple, and rapid laboratory testing method. This study aims to assess the clinical performance of MAGLUMI Denv NS1 in detecting dengue virus NS1 antigen.
A retrospective study was conducted to assess the sensitivity and specificity of MAGLUMI Denv NS1 using residual samples. Dengue-confirmed and excluded samples, validated by qPCR, were subjected to testing with MAGLUMI Denv NS1 in accordance with the manufacturer's instructions. The linear range, endogenous interference, and cross-reactivity of MAGLUMI Denv NS1 were verified, and a consistency analysis with commercial comparator products was carried out.
The diagnostic specificity of MAGLUMI Denv NS1 is 98.41% (62/63), and the sensitivity is 98.32% (117/119). It effectively detects various serotypes of dengue virus, with no observed endogenous interference or cross-reactivity. Additionally, the consistency of NS1, IgM, and IgG tests on the MAGLUMI platform compared to commercial comparator reagents reaches 85.71%, 99.25%, and 98.97%, respectively.
The MAGLUMI Denv NS1 represents a highly sensitive laboratory testing method capable of enhancing the diagnostic accuracy and efficiency of dengue virus infection detection.
登革热病毒感染的筛查与诊断在控制登革热疫情中起着关键作用，凸显了对一种高灵敏度、简单且快速的实验室检测方法的迫切需求。本研究旨在评估迈瑞登革热NS1检测试剂在检测登革热病毒NS1抗原方面的临床性能。
采用回顾性研究，使用剩余样本评估迈瑞登革热NS1检测试剂的灵敏度和特异性。经实时荧光定量聚合酶链反应（qPCR）验证的登革热确诊和排除样本，按照制造商说明用迈瑞登革热NS1检测试剂进行检测。验证迈瑞登革热NS1检测试剂的线性范围、内源性干扰和交叉反应性，并与商业对照产品进行一致性分析。
迈瑞登革热NS1检测试剂的诊断特异性为98.41%（62/63），灵敏度为98.32%（117/119）。它能有效检测登革热病毒的各种血清型，未观察到内源性干扰或交叉反应性。此外，与商业对照试剂相比，迈瑞平台上NS1、IgM和IgG检测的一致性分别达到85.71%、99.25%和98.97%。
迈瑞登革热NS1检测试剂是一种高灵敏度的实验室检测方法，能够提高登革热病毒感染检测的诊断准确性和效率。
