Diagnostic parameters and reliability of four rapid immunochromatographic tests for dengue 4

Braz. j. infect. dis; 24 (1), 2020
ABSTRACT Background: Although performance of rapid immunochromatographic tests (RITs) for dengue virus (DENV) serotypes 1, 2 and 3 is relatively settled, evidence on accuracy of RITs for DENV-4 are based on studies with small sample sizes and with discrepant results. Objectives: To assess accuracy and ...
