| Note: | Test Information: CMV by Quantitative NAAT, Plasma The Quantitative range of this assay for plasma is 1.54 - 7.00 log IU/mL or 34.5 - 10,000,000 IU/mL. An interpretation of "Not Detected" does not rule out the presence of inhibitors in the patient specimen or CMV DNA concentartion below the level of detection of the test. Care should be taken when interpreting any single viral load determination. Detected, not Quantifiable: CMV DNA detected, but at a level below 34.5 IU/mL (1.54 log IU/mL). CMV DNA concentration is below the lower limit of quantification of the assay. Indeterminate: Unable to generate a valid test result on this specimen. Please submit a new specimen for repeat testing if clinically indicated.

| When ordering tests for which Medicare or Medicaid reimbursement will be sought, physicians should only order tests that are medically necessary for the diagnosis or treatment of the patient. Components of the organ or disease panels may be ordered individually. The diagnostic information must substantiate all tests ordered and must be in the form of an ICD-10 code or its verbal equivalent. | |
