Dengue is a viral infection transmitted by the infected mosquito bite. High temperature, headache, rash, and joint and muscular discomfort are a few symptoms. In extreme circumstances, there may be life-threatening shock and extensive bleeding. The test for dengue antigen NS1, IgG, and IgM detects for the virus' non-structural protein component (NS1) as well as the antibodies (IgG & IgM) the immune system produces in response to the infection. Within 3–4 days of a dengue infection, NS1 and IgM are produced into the blood and are detectable.
