Evaluation of Two Immunoblot Assays and a Western Blot Assay for the Detection of Antisyphilis Immunoglobulin G Antibodies ▿

摘要

In the present study, two immunoglobulin G (IgG) immunoblot assays and one IgG Western blot assay were compared to the rapid plasma reagin test (RPR), the fluorescent treponemal antibody absorption test (FTA-ABS), and the Treponema pallidum particle agglutination assay (TP-PA). The agreement levels of the Viramed, Virotech, and MarDx assays were 97.0%, 96.4%, and 99.4%, and the agreements of samples inconclusive by FTA-ABS and resolved by TP-PA were 91.7%, 83.3%, and 69.4%, respectively.
