Herpes simplex DNA testing is more sensitive than culture for CSF and amniotic fluids.

Culture of the CSF for Herpes simplex will only be run in the setting of probable meningitis e.g. in disseminated infection in a newborn or for meningoencephalitis associated with genital herpes infection.

CSF culture will not be done in patients who present with an encephalitis only, for whom PCR is the appropriate test (see Herpes simplex, DNA).
