|---|---|
| Expected Results | Not detected |
| Test Limitations | A "Not detected" result may be the result of PCR inhibitors, virus levels below the level of detection of this test, or virus diluted in a large sampling volume. Virus quantitation is not possible due to the nature of the specimen. |
| Additional Information | A "Detected" result indicates the presence of CMV DNA. A result of "Not Detected" does not rule out the presence of CMV DNA or the absence of infection. False negative results may be due to the suppression of viral replication to levels below the detection threshold, or to inhibitory substances that may be present in the specimen. The performance characteristics of this test were validated by UWHC Clinical Laboratories. The U.S. Food and Drug Administration (FDA) has not approved or cleared this test; however, FDA approval or clearance is currently not required for clinical use of this test. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions. The UWHC Clinical Laboratories is authorized under Clinical Laboratory Improvement Amendments (CLIA) to perform high-complexity testing. |
