Cytomegalovirus, Quantitative PCR with Reflex to Drug Resistance Testing by Sequencing : 2006966

Mnemonic: CMV QNT GR

Methodology: Quantitative Polymerase Chain Reaction/Sequencing
Performed: Sun-Sat
Reported: 4-6 days
Specimen Required: Collect: Lavender (EDTA) or pink (K2EDTA).

Specimen Preparation: Separate plasma from cells. Transfer 4 mL plasma to a sterile container. (Min: 2.5 mL)

Storage/Transport Temperature: Frozen.

Unacceptable Conditions: Serum. Heparinized specimens.

Stability (collection to initiation of testing): Ambient: 8 hours; Refrigerated: 72 hours; Frozen: 1 year
Reference Interval:
Not detected
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.

Note: If CMV Quantitative PCR result is greater than or equal to 3.2 log (1600 copies/mL), then CMV Antiviral Drug Resistance by Sequencing will be added. Additional charges apply.
