Cytomegalovirus IgG

Elevated levels of CMV IgG in your blood suggest that your immune system has been actively fighting off a recent or reactivated Cytomegalovirus (CMV) infection. This can happen for various reasons, such as stress, a weakened immune system, or taking certain medications like corticosteroids or immunosuppressants that can lower your body's ability to fight infections. The presence of these antibodies means that your immune system has come across CMV before and has developed a way to defend against it. High levels of CMV IgG could be a sign that your body is working hard to keep you safe from this common virus.

Symptoms of high levels of CMV IgG may not be noticeable, as the immune response itself doesn't typically cause symptoms. However, if the CMV infection was recent or reactivated, you might experience fatigue, fever, sore throat, muscle aches, or swollen glands.

A low level of CMV IgG might mean that your body hasn't come across the Cytomegalovirus (CMV) before, which could be due to various reasons like your overall health, lifestyle, or simply not being exposed to the virus. It's also possible that your immune system isn't making enough of these antibodies, which could be influenced by factors like your age, how well-nourished you are, or certain medications you might be taking, such as immunosuppressants or corticosteroids. Having low CMV IgG levels doesn't necessarily mean you're in immediate danger, but it could suggest that your immune system might not be fully ready to fight off a CMV infection if you were to encounter the virus.

Symptoms of low levels of CMV IgG are typically non-existent, as this simply reflects a lack of prior exposure to the virus. However, if a person with low CMV IgG levels were to encounter the virus, they might experience symptoms of a primary CMV infection, which can range from no symptoms at all to fever, fatigue, and swollen glands.
