Sensitivity and specificity of different tests for the diagnosis of S. mansoni.

The study was carried out in three epidemiological settings of south Côte d'Ivoire in October and November 2010. Two different diagnostic ‘gold’ standards were applied to calculate sensitivity and specificity, namely (i) the combined results of nine Kato-Katz thick smears, and (ii) the combined results of all tests able to diagnose S. mansoni infections (i.e., nine Kato-Katz thick smears, one ether-concentration, three CCA-A, and one CCA-B).*Exact 95% confidence interval.
