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.
