Clinical uses of herpes simplex virus type-specific serology.

Type-specific serological tests to distinguish between infection with herpes simplex virus type 1 (HSV-1) and herpes simplex virus type 2 (HSV-2) have largely been used for studies which have contributed to our knowledge of the epidemiology and natural history of these infections. Such tests could be used as diagnostic tools in clinical situations provided that clinician and patient are aware of the test characteristics, which may result in false negative and false positive results. The use of serological tests in the screening of populations or sub-populations, such as pregnant women, has been advocated to attempt to halt the worldwide spread of the infection. However, there is little evidence currently to support this strategy.
