Dengue is a viral infection that affects millions of lives each year. A rapid screening test that would detect the NS1 antigen, IgM and IgG antibodies to recombinant antigens of all the dengue viruses helps in early detection of a potentially fatal disease. SD Bioline Duo, with the lateral flow technique, was employed in 24 cases of suspected dengue fever over a one-month period in a tertiary care hospital, with 14 cases (58.33%) testing positive. It helped in timely management of the cases and prevention of further complications of the viral disease.
