Order Code: C2562
ABN Requirement: No
Synonyms: CMV PCR
Specimen: EDTA Plasma
Volume: 2.0 mL
Minimum Volume: 1.0 mL
Container: EDTA (Lavender Top) tube, EDTA (Pink Top) tube
- Draw and gently invert 8 to 10 times.
- Centrifuge for 10 minutes.
- Pre-squeeze transfer pipet bulb and draw off approximately 2/3 of the upper plasma layer.
Note: This ensures that the buffy coat and red cells remain undisturbed.
- Aliquot plasma into labeled transport tube and cap tightly. Discard original tube.
- Store transport tube refrigerated at 2-8°C until ready to ship.
Special Instructions: Plasma must be separated from whole blood within 6 hours of collection by centrifugation. Transfer plasma to a sterile, screw-capped polypropylene tube. Store EDTA plasma refrigerated (2-8°C) once transferred. Specimen must be labeled with patient identifiers and submitted only for CMV testing.
Special Information: If EDTA plasma was not separated from red cells within 6 hours of collection and transported refrigerated, then the manufacturer’s requirements for the IVD reagent system have not been met and the following statements apply. “This test was developed and its performance characteristics determined by Cleveland Clinic’s Robert J. Tomsich Pathology and Laboratory Medicine Institute (RT-PLMI). It has not been cleared or approved by the FDA. RT-PLMI is regulated under CLIA as qualified to perform high complexity testing. This test is used for clinical purposes. It should not be regarded as investigational or for research.”
Transport: Store EDTA plasma at 2-8°C after collection and ship the same day per packaging instructions included with the provided shipping box.
Ambient (15-25°C): Not Acceptable
Refrigerated (2-8°C): 6 days
Frozen (-20°C): 12 weeks
Causes for Rejection: Specimens other than EDTA plasma; improper labeling; samples not stored properly; samples older than stability limits
Methodology: Polymerase Chain Reaction (PCR), Quant
Turn Around Time: 4-6 days

Clinical Significance: Detection and monitoring of CMV viral loads is indicated in patients at risk for progressive serious disease caused by this virus. Patients at risk include transplant recipients and patients with advanced HIV infection, among others. This test is used to monitor the amount of virus present in the blood of the patient and to initiate therapy or to suggest changing therapy.
