EVALUATION OF COMMERCIAL NEWER RAPID TEST FOR DETECTION OF EARLY ACUTE DENGUE INFECTION

Abstract

Introduction: We have done a study of evaluation of commercial newer rapid immunochromatographic test for diagnosis of early dengue infection. It detects both NS1 antigen and IgM antibody simultaneously.

Material and Methods: The test to detect dengue infection is done by rapid immunochromatographic test (ICT) which defect NS1 antigen and IgM antibody. [Advantage Dengue NS1 Ag and Ab Combi Card].

Results: Among 280 dengue suspected cases 78 were positive by rapid ICT. NS1 Among these 78 cases 57 were NS1 positive and 21 were IgM positive. All samples were tested for IgM ELISA.

Conclusion: Our findings support the use of diagnostic tools based on NS1 antigen detection positive for diagnosis of acute dengue virus infection. These rapid immunochromatographic tests allow rapid detection of the NS1 Ag and IgM antibody of dengue virus. Detection of the dengue NS1 Ag using the symptomatic phase of illness represents an important advanced in the diagnosis of dengue fewer. The immunochromatographic test Dengue NS1 antigen STRIP- The first rapid diagnostic test for early dengue virus infection- was highly sensitive and specific and would therefore be a suitable first line test in the field.
