Diagnostic accuracy of five serologic tests for Strongyloides stercoralis infection. [PDF]
BACKGROUND: The diagnosis of Strongyloides stercoralis (S. stercoralis) infection is hampered by the suboptimal sensitivity of fecal-based tests. Serological methods are believed to be more sensitive, although assessing their accuracy is difficult ...

Optimal classification and generalized prevalence estimates for diagnostic settings with more than two classes [PDF]
An accurate multiclass classification strategy is crucial to interpreting antibody tests. However, traditional methods based on confidence intervals or receiver operating characteristics lack clear extensions to settings with more than two classes. We address this problem by developing a multiclass classification based on probabilistic modeling and ...
