Know more about this test

The Cytomegalovirus, DNA PCR - Qualitative is a blood test that helps detect the presence of cytomegalovirus’s genetic material (DNA). This test helps identify active CMV infection, especially in individuals at high risk, such as immunocompromised patients, transplant recipients, and newborns.

Understanding Cytomegalovirus, DNA PCR - Qualitative

Cytomegalovirus (CMV) is a common virus that usually causes mild or no symptoms in healthy individuals. However, it can lead to severe disease in individuals with weak immune systems, such as transplant recipients. It can also be a concern to pregnant women who can pass the virus to babies, leading to congenital defects.

CMV can remain dormant in the body after the initial infection and may reactivate later, particularly in those with weakened immune defenses. The Cytomegalovirus, DNA PCR - Qualitative test directly detects the virus’s genetic material (DNA), making it a highly sensitive and specific method for identifying current CMV infections.

The Cytomegalovirus, DNA PCR - Qualitative test may be recommended if the individual exhibits symptoms such as prolonged high fever, fatigue, loss of appetite, muscle and joint pain, headache, sore throat, or enlarged liver or spleen. It is also done in vulnerable populations (including individuals with conditions like HIV/AIDS or organ transplantation, or in pregnant women) who are at higher risk of developing CMV-related complications.

Currently, there is no approved vaccine for CMV infection. Early detection and effective treatment are crucial to managing the condition and preventing serious complications in those most at risk of CMV infection.

Usually, no special preparation is needed for this test. Eat and drink as per the daily routine. However, it is preferred to provide the doctor with the clinical history before giving the sample.

Lab test results may vary across different laboratories. Abnormal test results require an expert interpretation. Therefore, never try to self-medicate at home based solely on these results, and always consult a doctor for a proper understanding of the test results.

Please note: This is an outsourced test. The sample for this test is collected by TATA 1MG and processed at a NABL accredited partnered lab.

What does Cytomegalovirus, DNA PCR - Qualitative measure?

The Cytomegalovirus, DNA PCR - Qualitative test measures the presence of Cytomegalovirus (CMV) genetic material (DNA) in an individual’s blood sample using the polymerase chain reaction (PCR) technique. This method amplifies even small amounts of viral DNA, allowing for early and accurate detection of CMV infection. A positive result indicates the presence of CMV DNA and confirms active infection or reactivation. A negative result suggests that no CMV DNA was detected, although repeat testing may be needed if symptoms persist or in high-risk cases, helping doctors make timely and informed decisions for managing CMV-related conditions.

Frequently booked together

FAQs related to Cytomegalovirus, DNA PCR - Qualitative

What is the Cytomegalovirus, DNA PCR - Qualitative test?

The Cytomegalovirus, DNA PCR - Qualitative test is a molecular diagnostic test that detects the presence of cytomegalovirus (CMV) DNA in the blood. It helps confirm an active or recent CMV infection.

Who should get this test?

This test is commonly recommended for individuals with weakened immune systems (e.g., HIV/AIDS patients, organ transplant recipients), pregnant women suspected of having CMV, newborns with symptoms of congenital infection, and anyone showing signs of an active CMV infection, such as prolonged fever, fatigue, or organ-specific symptoms.

How is the Cytomegalovirus, DNA PCR - Qualitative test performed?

A phlebotomist (a trained person who takes blood) will clean your skin with an alcohol swab and use a needle to draw blood from a vein. The sample is then safely stored and sent to a lab for testing.

Do I need to fast before taking the Cytomegalovirus, DNA PCR - Qualitative test?

No fasting is required for this test. You can schedule it at your convenience without avoiding food or water beforehand.

Is there any risk associated with the Cytomegalovirus, DNA PCR - Qualitative test?

No, the Cytomegalovirus, DNA PCR - Qualitative test is generally safe with minimal risks. However, you may feel slight discomfort during blood sample collection, but the chances of serious complications are extremely rare.

How is this test different from CMV antibody tests?

Unlike antibody tests that detect the body’s immune response to CMV, this test identifies the virus itself by detecting its genetic material (DNA), making it more accurate for diagnosing current infections.

Can you get a CMV infection twice?

Yes, individuals with weakened immune systems, such as transplant patients, may experience a recurrence or relapse of CMV.

How is CMV infection transmitted?

CMV can spread from one person to another in several ways: 1) From direct contact with saliva or urine, especially from babies and young children. 2) Through sexual contact. 3) From breast milk to nursing infants. 4) Through transplanted organs and blood transfusions.

How can CMV infection affect a pregnancy?

CMV can be transmitted from a pregnant woman to her unborn child. This can lead to congenital CMV infection.

What birth defects can be caused by CMV infection?

Babies born with a CMV infection can have serious long-term health problems, like hearing or vision loss. They may also have seizures, a small head, yellow skin, trouble with their liver, lungs, or spleen, and may face learning or developmental delays.

Is there a cure for CMV infection?

There is no cure, but there are medications that can help treat and ease the CMV symptoms.

How does Tata 1mg ensure accurate lab test results?
