The Cytomegalovirus Test helps detect CMV infections and related health concerns. It is a straightforward test with costs depending on the diagnostic center and location. Understanding the normal range is essential for accurate diagnosis. The procedure is safe, with only minor risks like mild pain or bruising during sample collection.
What is the Cytomegalovirus Test?
Cytomegalovirus (CMV) is a common yet often undiagnosed virus affecting millions worldwide. While many people experience no symptoms, it can pose severe risks to newborns, pregnant women, and immunocompromised individuals.
CMV is a herpes virus. Other forms of herpes viruses include chickenpox and mononucleosis (mono).
CMV infections are prevalent. The virus persists in the body for the remainder of one's life after the original infection. It is primarily latent but may reactivate under certain conditions such as stress or immune system issues.
Why is the Cytomegalovirus Test Done?
- CMV infections in healthy adults often result in mild or asymptomatic cases. Many individuals who have CMV are unaware of their infection.
- CMV can pose a significant risk to individuals with weakened immune systems, such as those with HIV or cancer.
- Pregnant women infected with CMV can pass the virus to their unborn child.
- CMV infection in newborns can lead to health issues such as deafness, eye problems, and intellectual disability.
- CMV tests help detect the presence of the virus in blood, sputum, or other bodily fluids.
- Testing for CMV helps identify at-risk patients and enable appropriate therapy.
- While there is no cure for CMV, antiviral medications and other treatments can alleviate symptoms.
