Cytomegalovirus by Quantitative NAAT, Plasma
Also known as: CMVQ
Use
This test is used to detect and quantify cytomegalovirus (CMV) in plasma. It is essential for monitoring CMV viral load, especially in immunocompromised patients such as organ transplant recipients, where viral load monitoring can guide therapeutic interventions.
Special Instructions
Specimen should be separated from cells within 24 hours of collection, and 2 mL plasma (minimum 1 mL) should be transferred to an ARUP standard transport tube. Use ARUP supply #15824, which can be ordered online through ARUP Connect. Ensure specimens are stored and transported frozen.
Limitations
An interpretation of 'Not Detected' does not rule out the presence of inhibitors or CMV DNA concentration below the detection level of the assay. International standardization has improved assay comparability across laboratories, but discrepancies might still exist due to commutability issues with the standard. Assay detects CMV DNA concentrations within 1.54-7.00 log IU/mL (34.5-10,000,000 IU/mL) range.
