Recent major outbreaks of Ebola virus disease in West Africa and the Democratic Republic of the Congo have emphasised the urgent requirement for rapid diagnostic tools to manage the illness. A clinical evaluation was conducted on QuickNavi-Ebola, an immunochromatography-based test kit developed previously. During outbreaks in the Democratic Republic of the Congo in 2018, researchers analysed 928 blood samples collected from individuals suspected of having Ebola virus disease. The performance of the test was benchmarked against the GeneXpert system approved by the World Health Organisation. Compared with GeneXpert-confirmed cases, QuickNavi-Ebola demonstrated a diagnostic sensitivity of 85 percent and a specificity of 99.8 percent. These performance metrics demonstrate that the kit provides practical reliability as a point-of-care diagnostic tool for detecting Ebola virus disease during active outbreaks.
Controlling deadly Ebola outbreaks requires rapid and dependable identification of infected individuals. Standard testing methods often require complex laboratory infrastructure. Demonstrating that an easy-to-use rapid diagnostic kit delivers high specificity and reliable sensitivity in real outbreak conditions enables health workers to diagnose suspected cases quickly at the point of care, improving response times and containment efforts.
The kit represents an applied and clinically tested diagnostic product designed for healthcare workers managing Ebola outbreaks. As a rapid immunochromatography-based tool, it serves as a point-of-care alternative or supplement to complex laboratory testing platforms like GeneXpert. Given its validated performance in a field trial with over 900 clinical samples, it appears near-market for emergency outbreak response and field diagnostics.

The recent large outbreaks of Ebola virus disease (EVD) in West Africa and the Democratic Republic of the Congo (DRC) have highlighted the need for rapid diagnostic tests to control this disease. In this study, we clinically evaluated a previously developed immunochromatography-based kit, QuickNavi<sup>TM</sup>-Ebola. During the 2018 outbreaks in DRC, 928 blood samples from EVD-suspected cases were tested with QuickNavi<sup>TM</sup>-Ebola and the WHO-approved GeneXpert. The sensitivity and specificity of QuickNavi<sup>TM</sup>-Ebola, estimated by comparing it to GeneXpert-confirmed cases, were 85% (68/80) and 99.8% (846/848), respectively. These results indicate the practical reliability of QuickNavi<sup>TM</sup>-Ebola for point-of-care diagnosis of EVD.
