Why we should use rapid dengue tests?

Dengue is a disease transmitted by the mosquito, and it is a disease that is spreading rapidly. The incidence of dengue is 30 times higher than it was half a century ago and now 40 percent of the global population is at risk. The illness can cause hemorrhagic fever, headaches, joint pain, and vomiting. Dengue cases are classified by the WHO as either dengue with or without warning signs or severe dengue. In pregnancy, a differential diagnosis of preeclampsia is important. Emerging evidence shows that severe dengue is associated with a high rate of fetal distress and cesarean delivery. Dengue may be transmitted in utero from mother to fetus.


THE SOLUTION

This dengue rapid test is available as an antigen-capture immunochromatographic test cassette. This in vitro assay is for qualitatively detecting Dengue NS1 antigen in human serum, plasma, and/or whole blood samples. Dengue NS1 antigen is a glycoprotein present in high concentrations in dengue-infected patients in the early clinical phase of the disease. The test is intended for professional use as a tool in the diagnosis of dengue virus infections.


To test, a sample of whole blood, plasma, or serum is added to the sample well of the test. The test works by detecting Dengue NS1 in the sample as it flows through the assay by first NS1 antibodies conjugated with colloidal gold that attach to HCG and provide a “visual tag” for the antigen-antibody-colloidal gold complex and second, by a test zone with immobilized antibodies that capture the complex, the visual tags producing a visible pink-colored band that is confirmation of the presence of NS1 and hence, a dengue infection. If there is no pink line, NS1 is not present, indicating a negative result for dengue. Results are ready in 10 minutes.
