Test Overview
Real-Time Polymerase Chain Reaction (PCR)
Useful for the detection of HSV encephalitis (differentiates HSV I from HSV II).
No Herpes simplex virus DNA detected
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
The result of this test should be correlated with serologic tests, patient symptoms, and clinical presentation. A single assay should not be the only criteria used to form a clinical conclusion. CSF obtained within 2-3 days after onset of HSV encephalitis symptoms can yield a false negative result and it is recommended that a repeat specimen be submitted if the clinical diagnosis strongly suggests this diagnosis.

Additional Information
The HSV PCR uses the polymerase chain reaction to amplify Herpes Simplex Virus-specific DNA sequences directly from the patient's CSF. Results should be used in conjunction with other laboratory test results and the patient's clinical profile.
