False-positive dengue non-structural protein 1 in pregnancy.

Dengue is a vector-borne infection, which contributes to significant morbidity and mortality in endemic areas. It manifests rapidly within 2 wk from febrile, critical to recovery phase. The point-of-care test (POCT) comprises the non-structural protein 1 (NS1) antigen, IgM and IgG, which aids rapid diagnosis, leading to timely treatment.
