Detection of herpes simplex virus in clinical specimens by an enzyme-linked immunosorbent assay.

An enzyme-linked immunosorbent assay (ELISA) for the detection of herpes simplex virus is described that can be performed in approximately four hours. The test, which does not require specialized equipment and uses relatively inexpensive, commercially available reagents, detected herpes simplex virus in 51% of specimens found to be positive by a time-consuming cell culture technic. The ELISA test compared favorably with a direct immunofluorescence method that detected HSV in only 1% of the cell culture-positive specimens. The ELISA test was readily carried out even with specimens unsuitable for cell culture and did not require cellular material as is the case with immunofluorescence technics. An advantage of the ELISA test for herpes simplex virus over the cell culture method was the detection of nonviable virus.
