Herpes Simplex I & II DNA, PCR, CSF

Useful For:
DNA testing is analytically more sensitive than culture, especially in patients with encephalitis or meningitis. DNA testing may be useful in diagnosis of infection in neonates. Neonates who have been exposed to HSV can develop disseminated infection and encephalitis. Encephalitis is usually due to HSV I whereas meningitis is usually due to HSV II. DNA testing provides reliable means to define the Type.
