What does it mean when you have low levels of Immunoglobulin G Qn Serum?

Immunoglobulin G (IgG) is the most common antibody in the body, and it is responsible for protecting the body from infection. IgG is produced by B cells in response to infection, and it can remain in the body for several months or even years.

Low levels of IgG can occur for a variety of reasons, including:

* Immunodeficiency disorders: Certain immunodeficiency disorders, such as common variable immunodeficiency (CVID), can lead to low levels of IgG. CVID is a rare disorder that affects the body's ability to produce antibodies.

* Infections: Some infections, such as measles, mumps, and rubella, can also cause low levels of IgG.

* Medications: Certain medications, such as corticosteroids and chemotherapy drugs, can interfere with the production of IgG.

* Aging: As people age, their levels of IgG naturally decline.

* Chronic diseases: Chronic diseases, such as cancer and diabetes, can also lead to low levels of IgG.

Low levels of IgG can make a person more susceptible to infection. They may also experience recurrent respiratory infections, ear infections, and skin infections. In some cases, low levels of IgG can lead to serious infections, such as pneumonia and sepsis.

If you have low levels of IgG, your doctor may recommend treatment with intravenous (IV) immunoglobulin (IVIG). IVIG is a preparation of antibodies that are taken from healthy donors. IVIG can help to boost your levels of IgG and protect you from infection.

Other treatments for low levels of IgG may include:

* Antibiotics to prevent infection

* Vaccinations to protect you from certain infections

* Lifestyle changes, such as avoiding contact with people who are sick and practicing good hygiene
