Order Code HSVC Herpes Simplex Virus (HSV), Molecular Detection, PCR, Spinal Fluid
Useful For
Aiding in the rapid diagnosis of herpes simplex virus (HSV)-1 and HSV-2 infections of the central nervous system
Method Name
Real-Time Polymerase Chain Reaction (RT-PCR)
Reporting Name
Herpes Simplex Virus, PCR, CSFSpecimen Type
CSFSpecimen Required
Supplies: Sarstedt Aliquot Tube, 5 mL (T914)
Container/Tube: Plastic vial
Specimen Volume: 0.2 mL
Collection Instructions:
1. Submit from second spinal fluid collection vial.
2. Transfer into aliquot vial using sterile technique.
3. Do not centrifuge or heat inactivate.
Additional Information:
1. The high sensitivity of amplification by polymerase chain reaction (PCR) requires the specimen to be processed in an environment in which contamination of the specimen by herpes simplex virus DNA is not likely.
2. Specimens that are received with less than the minimum volume required for all testing requested will be canceled.

Method Description
The Simplexa HSV (herpes simplex virus)-1 and -2 Direct assay system is a real-time polymerase chain reaction (PCR) that enables the direct amplification, detection, and differentiation of HSV-1 and HSV-2 DNA from unprocessed spinal fluid specimens without nucleic acid extraction.
In this assay, bifunctional fluorescent probe primers are used together with corresponding reverse primers to amplify HSV-1, HSV-2, and internal control targets. Well-conserved regions of the HSV-1 and HSV-2 DNA polymerase genes are targeted to identify HSV-1 and HSV-2 DNA, respectively, in the specimen. An internal control is used to detect PCR failure or inhibition.(Binnicker MJ, Espy MJ, Irish CL.
