Remarks
Clinical Utility: PCR of CSF specimens is now considered the 'gold standard' for the detection of HSV in patients with HSV encephalitis or other HSV-related central nervous system diseases such as recurrent meningitis. PCR can also be used to accurately diagnose HSV infections of the skin and mucous membranes and for the diagnosis of HSV neonatal disease. For diagnosis of neonatal HSV infection, collect specimens from skin vesicles, conjunctiva, mouth or nasopharynx, urine, blood, stool or rectum, and CSF. Detection of HSV from any of these sites more than 48 hours after birth may indicate active viral replication and infection of the infant rather than colonization after intrapartum exposure.
