The CMV DNA PCR test detects active cytomegalovirus infection by amplifying viral DNA in blood, helping diagnose and monitor CMV disease in high-risk individuals.
The CMV DNA PCR test is an advanced molecular diagnostic test that detects and quantifies cytomegalovirus (CMV) DNA in blood or plasma samples. CMV is a common virus that can cause serious infections especially in newborns, transplant recipients, and immunocompromised patients. Unlike antibody tests, the PCR-based test identifies the presence of the actual viral DNA, allowing early detection, monitoring of viral load, and guiding antiviral therapy. This test is critical for diagnosing active CMV infections and managing disease progression safely.
Why Is the CMV DNA PCR Test Important?
Early Detection: Identifies active CMV infections before symptoms worsen.
Monitoring: Tracks viral load in transplant patients to prevent complications.
High Sensitivity: Detects even very low levels of CMV DNA for accurate diagnosis.
Guides Treatment: Helps doctors decide when to start antiviral therapies.
Who Should Get Tested?
Newborns suspected of congenital CMV infection
Organ and stem cell transplant recipients
Immunocompromised individuals, including HIV patients
Pregnant women with CMV risk factors or symptoms
How Is the Test Performed?
A small blood sample is collected and processed in the lab using real-time PCR technology. This method amplifies the CMV DNA to detectable levels and quantifies viral load, providing detailed information about infection status.
Normal and Abnormal Results
Negative Result: No CMV DNA detected, indicating no active infection.
Positive Result: CMV DNA detected, confirming active infection or reactivation.
Viral Load Levels: Provide insight into infection severity and treatment response.
Cutting-edge PCR technology for highly sensitive and specific CMV DNA detection
Rapid turnaround with online result access
Experienced pathologists for reliable interpretation of viral load reports
Affordable packages tailored for prenatal, transplant, and immunocompromised patients
Convenient sample collection options with minimal discomfort
The test allows for early detection of CMV infections, monitoring of viral load, and assessment of treatment response, making it particularly valuable for high-risk populations.
The test involves collecting a sample (usually blood or urine), extracting the DNA, and amplifying it using polymerase chain reaction (PCR) to detect the presence of CMV.
If you test positive, your healthcare provider will discuss potential treatment options and further evaluations to manage the infection effectively.
The test is generally safe, but some individuals may experience mild discomfort or bruising at the site of blood collection. There are minimal risks associated with urine or tissue samples.
