A short description of the method used to perform the test
Quantitative Polymerase Chain Reaction
NY State Available
Indicates the status of NY State approval and if the test is orderable for NY State clients.
Lists a shorter or abbreviated version of the Published Name for a test
HHV-6A and HHV-6B
Lists additional common names for a test, as an aid in searching
HHV6 Quant PCR

Virus load monitoring
Describes the specimen type validated for testing
Defines the optimal specimen required to perform the test and the preferred volume to complete testing
Submit only one of the following:
Collect 1 mL spinal fluid (CSF) in sterile plastic container and ship frozen.
Draw blood in serum gel tube(s). Spin down and send 1 mL of serum frozen in a plastic vial.
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.
1. Source required.
2. Separate orders required for each specimen.
Specimen Minimum Volume
Defines the amount of sample necessary to provide a clinically relevant result as determined by the Testing Laboratory
Reject Due To
Identifies specimen types and conditions that may cause the specimen to be rejected
| Hemolysis || Mild OK; Grossly Reject |
| Lipemia || NA |
| Icterus || NA |
| Other || Heparinized specimens, Stool, tissues in optimal cutting temperature compound. |
Specimen Stability Information
Provides a description of the temperatures required to transport a specimen to the performing laboratory, alternate acceptable temperatures are also included
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
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.
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances
No international standard is currently available for calibration of this assay. Caution should be taken when interpreting results generated by different assay methodologies.

Provides information regarding the medical device classification for laboratory test kits and reagents. Tests may be classified as cleared or approved by the US Food and Drug Administration (FDA) and used per manufacturer instructions, or as products that do not undergo full FDA review and approval, and are then labeled as an Analyte Specific Reagent (ASR) product.
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.
CPT Code Information
Provides guidance in determining the appropriate Current Procedural Terminology (CPT) code(s) information for each test or profile. The listed CPT codes reflect Mayo Clinic Laboratories interpretation of CPT coding requirements. It is the responsibility of each laboratory to determine correct CPT codes to use for billing.
CPT codes are provided by the performing laboratory.
Provides guidance in determining the Logical Observation Identifiers Names and Codes (LOINC) values for the order and results codes of this test. LOINC values are provided by the performing laboratory.
