Clinical Information
Herpes simplex virus (HSV) types 1 and 2 are members of the Herpesviridae family and produce infections that may range from mild stomatitis to disseminated and fatal disease. Clinical conditions associated with HSV infection include gingivostomatitis, keratitis, encephalitis, vesicular skin eruptions, aseptic meningitis, neonatal herpes, genital tract infections, and disseminated primary infection.
Infections with HSV types 1 and 2 can differ significantly in their clinical manifestations and severity. HSV type 2 primarily causes urogenital infections and is found almost exclusively in adults. HSV type 1 is closely associated with orolabial infection, although genital infection with this virus can be common in certain populations.
The diagnosis of HSV infections is routinely made based on clinical findings and supported by laboratory testing using polymerase chain reaction or viral culture.
Reference Values
HERPES SIMPLEX VIRUS (HSV)-1
Negative
HERPES SIMPLEX VIRUS (HSV)-2
Negative
Interpretation
This is a qualitative assay; results are reported either as negative or positive for herpes simplex virus (HSV) type 1, HSV type 2, or HSV type indeterminate. Results can also be reported as invalid.
An indeterminate result indicates that HSV DNA was detected but the assay is unable to differentiate between HSV-1 and HSV-2. If typing is required, it is suggested that a new specimen be collected for testing by an alternate method.
An invalid result points to the inability to determine presence or absence of HSV-1 or HSV-2 DNA in the sample.
Detection of HSV DNA in clinical specimens supports the clinical diagnosis of infection due to the virus.
