Test 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, CSF

Specimen Type

CSF


Specimen 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.


Specimen Minimum Volume

0.1 mL

Specimen Stability Information

Specimen Type Temperature Time Special Container
CSF Refrigerated (preferred) 7 days
  Frozen  7 days

Reference Values

Negative

Interpretation

A positive result suggests the presence of herpes simplex virus (HSV)-1 and/or HSV-2 DNA in the cerebrospinal fluid (CSF) sample.

 

A negative result suggests that HSV-1 and HSV-2 DNA are not present in the CSF sample.

 

An invalid result points to the inability to determine presence or absence of HSV-1 or HSV-2 DNA in the CSF sample.
