Interpretive Data

The quantitative range of this assay is 3.0- 7.0 log copies/mL (1,000-10,000,000 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 Adenovirus DNA 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 assay methodologies.

Compliance Category

Analyte Specific Reagent (ASR)

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."
