Cytomegalovirus, Quantitative PCR with Reflex to Drug Resistance Testing by Sequencing
Detect and quantify cytomegalovirus. Determine antiviral drug resistance to cidofovir, foscarnet sodium, and ganciclovir.
Quantitative Polymerase Chain Reaction/Sequencing
New York DOH Approval Status
Lavender (EDTA) or pink (K2EDTA).
Separate plasma from cells. Transfer 4 mL plasma to a sterile container. (Min: 2.5 mL)
Serum. Heparinized specimens.
Ambient: 8 hours; Refrigerated: 72 hours; Frozen: 1 year
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)
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.
