| CMV by PCR (8000100193) | |
|---|---|
| Test Mnemonic: | |
| Specimen Requirements: | |
| Collection: | Plasma Pearl Top (PPT) - blood or Sterile Container - urine |
| Container: | PPT for blood; Sterile Container for urine |
| Minimum Volume: | 4 mL plasma or 4 mL urine |
| Storage/Transport: | Refrigerate 2-8C up to 5 days. If there are delays, samples should be frozen (<-20C). |

| Stability: | 5 days |
| Causes for Rejection: | Incomplete and/or incorrect sample identification, insufficient sample collection, gross hemolysis, clotted samples, incorrect tube type, non-sterile or leaking containers |
| Reference Range: | <300 IU/mL |
| Turnaround Time: | Test is performed three days per week. |

| Performed: | |
| Lab: | Clinical Microbiology |
| Synonyms: | CMV Quantitative viral load; Cytomegalovirus viral load; CMV Viral Load; CMV PCR test |
| Clinical Indication: | To monitor active CMV infections |
| Patient Preparation : | Routine venipuncture for blood. Routine urine collection. |
| CPT 4 Code: | 87497 |
| Note: | This assay measures cytomegalovirus (CMV) DNA using real-time PCR. The dynamic range of the assay is 300 - 3,000,000 IU/mL. A result of <300 IU/mL does not rule out the presence of PCR inhibitors in the patient's specimen or that CMV virus DNA concentrations may be below the level of quantification. Care should be taken when interpreting any single viral load determination and the test is intended for use in conjunction with clinical presentation and other laboratory results. |
| 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. | |
