Test Details: This testing is indicated to diagnose dengue fever when patient has symptoms such as high grade fever, abdominal pain and Vomiting. Dengue Virus non-structural protein 1 (NS1) is detectable during the acute phase of dengue virus infections, prior to IgM seroconversion. NS1 antigenemia is detectable within 24 hours and up to 9 days following symptom onset. The IgM become detectable on Day 3 to 5 of illness in case of primary dengue infection and persist for 2 to 3 months, whereas IgG appear by the fourteenth day and persist for life. Concurrent evaluation for the NS1 antigen alongside testing for IgM- and IgG-class antibodies to Dengue Virus provides optimal diagnostic potential for both early and late dengue disease detection.
