Cytomegalovirus (CMV) Avidity, IgG in Begumpet, Hyderabad

Cytomegalovirus (CMV) is a common virus that belongs to the herpes family. On average, every person gets infected by this virus at least once by the time they reach 40 years of age. This virus can remain dormant in your body for a long time. It is also possible that you can catch the infection during childhood, teenage, or even during adulthood with no distinct symptoms. In most cases, the virus remains inactive and causes symptoms only when it experiences stress in the immune system.

In such a scenario, the CMV avidity test is essential to detect the presence of cytomegalovirus. This is because the virus can quickly spread through the saliva of one person and can cause cold sores. The cytomegalovirus test is essential for people with a weak immune system as they may suffer from severe symptoms of the infection.

Different types of CMV infections can affect an individual at various stages:

• Congenital: This infection is usually inherited from maternal blood and affects a baby before it is born.
• Primary: It is the first infection from CMV that an individual suffers at any point in their lifespan. Usually, it seems like mononucleosis due to its symptoms.
• Reactivation: A reactivation of CMV is a secondary infection where the virus activates itself after remaining dormant for a period. These infections can also result from HIV infection, cancer treatment, and organ transplantation.
