Laboratory Studies

Scrapings from suspected lesions of herpes simplex (Tzanck smear). This is not a reliable screening test, with a reported sensitivity of 65%. It also does not identify the type of herpes simplex virus (HSV) present.

  • Multinucleated giant cells, as shown in the image below

  • Intranuclear inclusions

Viral culture from skin vesicles (more sensitive that Tzanck smear but dependent on duration of viral shedding)

Monoclonal antibody testing

Serology

Cerebrospinal fluid (CSF) analysis for lymphocytic pleocytosis

  • Bloody CSF
  • Polymerase chain reaction (PCR) detects HSV DNA
Next

Imaging Studies

CT scan and MRI for differentiation of encephalitis from other entities

Procedures

Slit-lamp examination for dendritic keratitis with ocular involvement

Lumbar puncture, if concerned about encephalitis

Brain biopsy, if encephalitis is considered
