Dengue NS1 kit is an immunochromatographic technique for rapid detection of dengue virus antigen in patient's serum. It is highly appreciated for having ability to detect infection just from 1st day after onset. This kit requires 100 micro liter of blood or serum sample with test completion time of 15 to 20 minutes. Dengue NS1 is provided with conjugated antibody that is specific to virus antigen which shows color change for positive test. It is known to have up to 92.4% of sensitivity and 98.4% of specificity. This is an enzyme linked immunosorbent assay detection method of nonstructural protein 1 and helps in providing timely treatment before it emerges to a deadly state.
