Roche has obtained CE mark approval for its fully automated immunoassay, Elecsys Dengue Ag test, intended for diagnosing acute infection.

The assay detects the virus’ non-structural protein 1 (NS1) antigen in human serum and plasma, a key indicator of acute infection in the initial days of illness.

According to Roche, the test identifies this antigen across all four serotypes of dengue virus, DENV-1, DENV-2, DENV-3 and DENV-4.
