Real-Time Polymerase Chain Reaction (PCR)
Measures the CMV viral load present at the time of specimen collection. Used as an aid in determining or altering treatment in CMV infected, immunocompromised patients.
Not detected in uninfected patients. Patients with latent infection may have a detectable viral load at baseline.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
Collect specimen in a lavender top (EDTA) tube. Centrifuge for 20 minutes at 800 - 1600 xg at room temperature and aliquot plasma into a polypropylene plastic vial within 24 hours of collection. Refrigerate for up to 5 days or freeze for longer storage. Do not allow frozen specimens to thaw at any time during storage or transport, due to possible degradation of the DNA. Specimens submitted in polystyrene tubes are not acceptable. Specimens sent for Microbiology molecular testing require a dedicated sample and cannot be shared with other laboratories.
