Cat. No : 11FK45. SD BIOLINE Dengue Duo (Dengue NS1 Ag + IgG/IgM) The SD BIOLINE Dengue Duo kit is a rapid, an in-vitro immunochromatographic, one step assay designed to detect both dengue virus NS1 antigen and antibodies to Dengue virus (Dengue IgG/IgM) in human serum, plasma or whole blood. SD BIOLINE Dengue Duo rapid test contains two test devices (left side ; Dengue NS1 Ag test, right side ; Dengue IgG/IgM test). The SD BIOLINE Dengue Duo kit is intended only for an initial screening test and reactive samples should be confirmed by a supplemental assay such as RT-PCR, IgM / IgG ELISA or HI (Hemagglutination inhibition) test. Detect Dengue Ag and Ab simultaneously at once. Cover acute to convalescence stage Performance: Sensitivity : 92.4% (Dengue NS1 Ag), 94.2% (Dengue IgG/IgM) Specificity : 98.4%(Dengue NS1 Ag), 96.4% (Dengue IgG/IgM) In primary infection with the dengue virus, IgG antibody appears a few days after IgM. In primary infections, IgG antibodies are produced at a lower level compared to IgM but will persist for many years after infection. In secondary infections, IgG response may rise quickly before or simultaneously with an IgM response and will become the predominant immunoglobulin isotype in secondary infections.
