Roche gets CE mark for Elecsys Dengue Ag test to diagnose dengue
Basel: Roche has announced that it has received CE mark for its Elecsys Dengue Ag test - a high-throughput, fully automated immunoassay to be used as an aid in the diagnosis of an acute dengue virus infection.
Dengue fever is the most common mosquito-borne viral illness in the world. In 2024, more cases of dengue were recorded than ever before in a 12-month period, affecting over 100 countries on all continents. During 2024, ongoing transmission, combined with an unexpected spike in dengue cases, resulted in a historic high of over 14.6 million cases and more than 12,000 dengue-related deaths. Over the past 50 years, the spread of the disease has accelerated, posing a significant global health threat as half of the world's population now lives in areas at risk of infection.
The symptoms of dengue aren't unique, so doctors often struggle to distinguish it from other fever-causing illnesses, such as chikungunya or yellow fever. This is why early and accurate diagnosis is critical so that patients can be managed in a timely manner to prevent severe complications.
The Elecsys Dengue Ag is an in-vitro diagnostic immunoassay for the qualitative detection of the NS1 antigen of the dengue virus in human serum and plasma, a key marker of acute infection during the first days of illness. It is intended for use on Roche’s fully automated cobas e immunoassay analysers: cobas e 801 systems and cobas e 402 platforms – a widely used platform with an extensive installed base in laboratories worldwide.
The test has been shown to reliably detect NS1 antigen for all four dengue virus serotypes – DENV-1, DENV-2, DENV-3, and DENV-4.4 In clinical studies, it demonstrated 94.90% (CI: 91.44–97.26%) sensitivity in PCR-confirmed positive samples and 99.96% (CI: 99.79–100%) relative specificity in a large cohort of healthy blood donors.
“Dengue’s rapid worldwide spread has elevated it to a serious global burden, placing a significant strain on healthcare resources,” said Matt Sause, CEO of Roche Diagnostics. “Roche is committed to supporting the global response to the rise of infectious diseases such as dengue. With our novel Elecsys Dengue antigen test, we enable healthcare systems to diagnose dengue more reliably and efficiently.”
Recognising the value of diagnostics, the World Health Organization (WHO) has developed an “Essential Diagnostics List” which includes in-vitro diagnostic solutions that should be accessible to all countries to increase timely and life-saving diagnoses. Dengue virus NS1 antigen, along with other biomarkers, is included in the WHO essential IVD list.
