Interpretive Data
The quantitative range of this test 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.

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

See Compliance Statement A: www.aruplab.com/CS
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.
