Diagnos Dengue Card

Diagnos Dengue card is a rapid solid phase Immuno-chromatographic test for the qualitative differential detection of IgM and IgG antibodies to dengue virus in Human serum /Plasma. This test is for in vitro diagnostic use only and is intended as an aid in for presumptive diagnosis between primary and secondary dengue infection.

Diagnos Dengue card test is based on immunochromatographic test principle for the differential detection of Dengue IgM/IgG antibodies.

Dengue IgM/IgG test device contains three lines; “C” (Control line), “M”(IgM test line) & “G”(IgG test line).IgM test line is coated with anti-human IgM and IgG test line is coated with anti-human IgG.When a sample is added to the device,IgG and IgM antibodies in the sample react with red particles coated with Dengue proteins. As this sample/particle mixture migrates along the length of the test, the anti-dengue IgG or IgM antibody particle complex is captured by the relevant IgG and /or IgM test bands located in the test device window causing a pale to dark red band to form at the IgG or IgM Region of the test device window. The intensity of the test bands in the device will vary depending upon the amount of antigen /antibody present in the sample. The appreance of any pink/ red colour in a specific test region should be considered as positive for that particular antigen and/or antibody type (IgG or IgM). A red procedural control line should always develop in the test device window to indicate that the test has been performed properly.

Within-run(Intra assay) and between-run (Interassay) precisions have been determined by testing 10 replicates of five specimens: one negative. Two dengue IgM positive and Two Dengue IgG positive. The C.V (%) of all the five samples were within 10 % of the time.
