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.
