Cytomegalovirus Antiviral Drug Resistance by Sequencing
Copy Utility
Determine antiviral drug resistance to cidofovir, foscarnet sodium, and ganciclovir.
Polymerase Chain Reaction/Sequencing
Sun-Sat
2-3 days
Lavender (EDTA), pink (K2EDTA) or plasma preparation tube.
Separate plasma from cells within 8 hours. Transfer 4 mL plasma to an ARUP Standard Transport Tube. (Min: 1.5 mL)
Frozen.
Heparinized specimens.
Please submit most recent viral load and test date, if available.
Ambient: 8 hours; Refrigerated: 72 hours; Frozen: 1 month
Codons 457-630 of the UL97 gene and codons 393-1000 of the UL54 gene are sequenced. Mutations associated with resistance to ganciclovir, cidofovir, and foscarnet are reported. Mutations in viral sub-populations below 20 percent of total may not be detected.
Compliance Statement B: For laboratory developed tests not using a RUO kit, and for FDA approved, cleared or 510(k) exempt assays with alterations. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.
This test may be unsuccessful if the plasma CMV DNA viral load is less than 1,500 CMV DNA copies per mL of plasma.
