![]() Prospective evaluation of an algorithm incorporating HSV-1 serostatus found that 11 of 70 persons with indeterminate HSV-2 ELISAs were Western blot-positive.Ĭlinicians should consider selectively using a higher index value to define Focus ELISA HSV-2 positivity based on either HSV-1 serostatus or clinical circumstances. Selectively raising the ELISA index value defining HSV-2 positivity from >1.1 to >or=3.0 either among HSV-1-positive men or among those without a history or clinical evidence of genital lesions increased the PPV to >or=93%. Western blot positivity was more common in men without herpes simplex virus type 1 (HSV-1) antibody than in those with HSV-1 antibody (93% vs 76%, P = 0.02) and in men with a history or clinical evidence of genital lesions (88% vs 80%, P = 0.30). Ninety-one (84%) of 108 HSV-2 ELISA-positive sera tested HSV-2 Western blot-positive. HSV-1 and HSV-2 can be identified simultaneously with a single test. Herpes simplex 1 IgG, IgM (Western Blot), Herpes simplex 2 IgG, IgM (Western Blot), HIV (1+2) combi PT (Ag24+Ab) (ELISA). A subset of sera from each site was then selected, based on the HSV-2 results, and tested by Western blot (WB). HSV-2 Western blots were then prospectively performed on sequential sera with indeterminate HSV-2 ELISAs. There is thus a window of approximately 47 days in which the Western blot assay may give false-negative confirmatory results. Westernblot is considered the gold standard for differentiation between HSV-1 and. All herpesviruses are composed of relatively large DNA genomes. HSV-2 Western blots were performed on sera from male sexually transmitted disease clinic patients testing HSV-2 ELISA-positive and used to define a new class of indeterminate HSV-2 ELISA result. A subset of sera from each site was then selected, based on the HSV-2 results, and tested by Western blot (WB). Herpes simplex virus type 1 and type 2 (HSV-1 and HSV-2) are pathogenic to humans and belong to the herpesvirus family. Herpes simplex virus type 2 (HSV-2) Western blot confirmatory testing among men testing positive for HSV-2 using the focus enzyme-linked immunosorbent assay. If you think you may have a medical emergency, call your physician or 911 immediately.The objective of this study was to define the positive predictive value (PPV) of the Focus herpes simplex virus type 2 (HSV-2) enzyme-linked immunosorbent assay (ELISA) in a low HSV-2 prevalence population and to develop a new test interpretation algorithm.
