Usefulness of Commercial Rapid Test Kits as an Effective Diagnostic Tool of Dengue Virus Infection in a Low Resource Setting | Chapter 09 | Theory and Applications of Microbiology and Biotechnology Vol. 2
Rapid immuno-chromatographic tests (ICTs) or diagnostic kits that are commercially available were evaluated for their sensitivity, specificity, cost and turnaround time (TAT) results with Dengue IgM/IgG capture enzyme linked immunosorbent assays (ELISA) as the standard test, in blood samples from a cross-section of individuals with clinical features suggestive of dengue fever attending health care facilities in Trinidad and Tobago. Blood samples taken from 100 consented participants were analyzed using the two rapid ICTs (SD Bioline Dengue Duo NS1/IgM/IgG and Panbio Dengue Duo Cassette) and compared with the Dengue IgM/IgG capture ELISAs. Standardized questionnaire was used to obtain bio and epidemiological data of the participants. The laboratory evaluation also assessed the TAT to complete the tests as well as the cost for each test method. The laboratory analysis on a given number (n=93) revealed that the SD Bioline was more sensitive (39.9%) than the Panbio (22.1%; p=0.005), and ...
