Detect and quantify cytomegalovirus. Determine antiviral drug resistance to cidofovir, foscarnet sodium, and ganciclovir.
- Patient Preparation
- 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
- Unacceptable Conditions
- Serum. Heparinized specimens.
- Ambient: 8 hours; Refrigerated: 72 hours; Frozen: 1 year
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.
