Clinical Information

Herpes simplex virus (HSV) types 1 and 2 cause a variety of clinical syndromes. Anatomic sites infected include the skin, lips, oral cavity, eyes, genital tract, and central nervous system. Systemic disease may also occur, in which the virus may be detectable in the bloodstream. The detection of HSV-1 or HSV-2 DNA from blood specimens may help support the diagnosis of disseminated disease associated with this virus.

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 means that HSV DNA was detected but the assay was unable to differentiate between HSV type 1 and HSV type 2. If typing is required, it is recommended that a new specimen be collected and tested 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.
