Abstract
A new direct herpes simplex virus antigen enzyme immunoassay (EIA) uses a special EIA transport medium (ETM) for transport of herpes simplex virus (HSV) specimens. As ETM lyses the virus precluding culture and typing, we evaluated the relative performance of this EIA when performed on specimens transported in either ETM or a standard viral transport medium (VTM). These EIA results were also compared to cell culture performed on specimens transported in VTM (VTM-CC) and direct rapid inoculation into cell culture (CC). Based on all confirmed positives, by any test, the sensitivities for CC was 97% ( 66 68 ), for VTM-CC 91% ( 62 68 ), for ETM-EIA 97% ( 66 68 ), and for VTM-EIA 93% ( 63 68 ). It appears that VTM may be a slightly less desirable substitute than ETM in the performance of EIA. However, VTM-EIA is certainly as sensitive as cell culture performed on VTM.
