Advantage Dengue NS1 Ag card test is based on immunochromatographic test principle for the detection of Dengue NS1 antigen. When a sample is added to the device, Dengue NS1 Antigen if present in the sample will bind to the anti-dengue NS1 gold colloidal conjugate making antigen antibodies complex. This complex migrates along the membrane to the test region and forms the visible pink line at “T” as antibody-antigen-antibody gold colloid forms.
The intensity of the test bands in the device will vary depending upon the amount of antigen 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. A red procedural control line should always develop in the test device window to indicate that the test has been performed properly.
