Evaluation of an immunochromatographic point-of-care test for the simultaneous detection of nontreponemal and treponemal antibodies in patients with syphilis.

We described the evaluation of the Syphilis Screening & Confirm Assay for the simultaneous detection of nontreponemal and treponemal antibodies. A total of 248 samples were evaluated. The sensitivity of the tests was 98.8%, 99.5% and 98.9%, while specificity was 94.7%, 88.9% and 93.2%, respectively, as compared with the rapid plasma reagin, Treponema pallidum hemagglutination assay, and fluorescent treponemal antibody absorption tests.
