Second, because when we evaluated the RDT performance on convalescent-phase samples for a subset of 30 dengue-confirmed patients with negative IgM RDT results in the acute-phase sample, we only found 13 positive samples (none positive by the NS1 component and 13 positive by the IgM component), indicating a convalescent-phase sensitivity for the RDT test of only 43.3%. This evidence concerns the gene CD40LG and dengue disease.
