Interpretive Data
The quantitative range of this test is 2.6- 6.6 log copies/mL (390-3,900,000 copies/mL) or 2.4- 6.4 log IU/mL (227- 2,270,000 IU/mL). One IU/mL of CMV DNA is approximately 1.72 copies/mL.
A negative result (less than 2.6 log copies/mL [less than 390 copies/mL] OR less than 2.4 log IU/mL [less than 227 IU/mL]) does not rule out the presence of PCR inhibitors in the patient specimen or CMV DNA concentrations below the level of detection of the test. Inhibition may also lead to underestimation of viral quantitation.
This test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.
Analyte Specific Reagent (ASR)
Note
The limit of quantification for this DNA test is 2.6 log copies/mL (390 copies/mL) or 2.4 log IU/mL (227 IU/mL). If the test DID NOT DETECT the virus, the test result will be reported as "<2.6 log copies/mL (<390 copies/mL)" and "<2.4 log IU/mL (<227 IU/mL)." If the test 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."
