Submit only one of the following:

 

CSF:

Collect 1 mL spinal fluid (CSF) in sterile plastic container and ship frozen.

 

Serum:

Draw blood in serum gel tube(s). Spin down and send 1 mL of serum frozen in a plastic vial.

 

Plasma:

Draw blood in lavender (EDTA), pink (K2EDTA) tube(s), or (yellow ACD) tube(s). Spin down and send 1 mL of plasma frozen in a plastic vial.

 

Note:

1.     Source required.

2.     Separate orders required for each specimen.

Specimen Type

Varies

Specimen Minimum Volume

0.5 mL

Specimen Stability Information

Specimen Type Temperature Time

Reference Values

Not detected

 

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 test. Inhibition may also lead to underestimation of viral quantitation.

Cautions

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

Day(s) Performed

Tuesday through Saturday

Test Classification

Analyte specific reagents (ASR) are used in many laboratory tests necessary for standard medical care and generally do not require U.S. Food and Drug Administration (FDA) approval or clearance. This test was developed and its performance characteristics determined by ARUP Laboratories. The U.S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions. This test should not be regarded as investigational or for research use.
