Description
Why It’s Done:
The CMV DNA Quantitative Test is done to:
• Quantify the amount of CMV virus in a patient’s body, helping to evaluate the activity of the infection.
• Monitor CMV reactivation in high-risk patients, particularly organ transplant recipients, HIV-positive individuals, and those undergoing chemotherapy.
• Track the effectiveness of antiviral therapy, determining if treatment is reducing viral replication.
• Assess the risk of CMV disease or complications due to viral load (high viral load may correlate with increased risk of CMV-related illness).
• Diagnose congenital CMV infection in newborns when paired with other tests.
Unlike the qualitative PCR test, which only detects the presence of CMV, this test provides a quantitative measurement, making it valuable for tracking infection progress and treatment decisions.
Preparation:
• No fasting or special preparation is needed before the test.
• A blood sample or other relevant fluid (e.g., urine or saliva) will be collected.
• Inform your healthcare provider if you are taking antiviral medications, as these can influence the results.
• Discuss with your provider if you’ve recently had a CMV infection, transfusion, or organ transplant
