Detection of Herpes Simplex Virus Type 2-Specific Immunoglobulin G Antibodies in African Sera by Using Recombinant gG2, Western Blotting, and gG2 Inhibition
ABSTRACT
Sera from 1,238 Vietnamese women in Hanoi were tested for herpes simplex virus type 2 (HSV-2). HSV-2 prevalence was 2.0%. The Kalon and Biokit assays showed significantly higher concordance to Western blotting data than did the Focus assay (P < 0.01). Screening by Focus and then retesting with Kalon/Biokit of positive samples can reduce falsely positive results significantly (P < 0.01).
