RESUMO
Recently a few new herpes simplex virus (HSV) type-specific serological diagnostic tests have been introduced to the commercial market, but these tests have some limitations. Moreover, it is not yet clear which commercial test can be regarded as a “gold standard” for the serodiagnosis of HSV infections. In order to improve the clinical diagnostic value of serological tests for the detection of HSV infections, we developed novel, competition-based enzyme-linked immunosorbent assays for the specific determination of HSV type 2 antibodies (SeroHSV2) and HSV type 1 antibodies (SeroHSV1) and two complementary tests for the detection of HSV immunoglobulin M (IgM) and IgG antibodies (SeroHSV IgM and SeroHSV IgG). These four new kits were evaluated in comparison with some commercial kits for the detection of HSV antibodies that are commonly used at present in Israeli clinical laboratories. The results indicate that SeroHSV2 is highly sensitive (>92%) and highly specific (>94%). SeroHSV2 does not cross-react with other alphaherpesvirus antibodies. SeroHSV1 is highly sensitive (>94%) and specific (>91%) compared to four commercial available kits. SeroHSV IgM is highly specific (>92%) in comparison with other commercial HSV IgM tests. The sensitivity of SeroHSV IgM ranges between 50 and 70% compared to these tests. Further investigation of the discrepant results obtained by using in-house competition tests indicated that SeroHSV IgM is more sensitive. SeroHSV IgG was also found to be highly sensitive (>94%) and highly specific (>92%) compared to the other commercial HSV IgG tests.
