Ngo TD, Laeyendecker O, Morrow RA, Lai S, Quinn TC. Comparison of three commercial immunoassays for detection of herpes simplex virus type 2 antibodies in commercial sex workers in Yunnan Province, China. Clin Vaccine Immunol. 2008, 15: 1301-3 PMCID: 2519307.
Five hundred commercial sex workers in China were tested for herpes simplex virus type 2 by three immunoassays and Western blotting. Sensitivities for the Focus, Kalon, and Biokit assays were 86.7%, 82.3%, and 34.9%, respectively, and specificities were 91.8%, 94.2%, and 60.1%, respectively. The Focus assay performed optimally at an index of 1.5 (95.2% sensitivity and 93.4% specificity), and the Kalon assay performed optimally at an index of 1.2 (93.3% sensitivity and 95.2% specificity).
