Herpesvirus 6 (HHV6) (A&B), Quantitative PCR : 0060071

Mnemonic: HHV6PCR

Methodology: Quantitative Polymerase Chain Reaction
Performed: Mon, Wed, Fri
Reported: 2-7 days
Specimen Required: Collect: Lavender (EDTA) or pink (K2EDTA). OR CSF.

Specimen Preparation: Separate plasma from cells.
Transfer 1 mL plasma or CSF to a sterile container. (Min: 0.5 mL)


Storage/Transport Temperature: Frozen.

Submit specimen according to Biological Substance, Category B, shipping guidelines.


Remarks: Specimen source required.

Unacceptable Conditions: Heparinized specimens. Hemolyzed specimens.

Stability (collection to initiation of testing): Ambient: 8 hours; Refrigerated: 72 hours; Frozen: 3 months
Reference Interval:
Not detected
Interpretive Data: The quantitative range of this assay is 3.0-6.0 log copies/mL (1,000-999,000 copies/mL)

A negative result (less than 3.0 log copies/mL or less than 1,000 copies/mL) does not rule out the presence of PCR inhibitors in the patient specimen or HHV6 DNA in concentrations below the level of detection of the assay. Inhibition may also lead to underestimation of viral quantitation.

No international standard is currently available for calibration of this assay. Caution should be taken when interpreting results generated by different methodologies.


This test is performed pursuant to an agreement with Roche Molecular Systems, Inc.

Refer to Statement A under Testing Information at http://www.aruplab.com.
Note: The limit of quantification for this DNA assay is 3.0 log copies/mL (1,000 copies/mL). If the assay DID NOT DETECT the virus, the test result will be reported as "<3.0 log copies/mL (<1,000 copies/mL)." If the assay DETECTED the presence of the virus but was not able to accurately quantify the number of copies, the test result will be reported as "Not Quantified."

This assay detects and quantifies HHV6 subtypes A and B.
CPT Code(s): 87533
