Immunoglobulin G: IgG is the most common type of antibody in your blood and other body fluids. These antibodies protect you against infection by "remembering" which germs you've been exposed to...

An IgG deficiency is a health problem in which your body doesn’t make enough Immunoglobulin G (IgG). People with IgG deficiency are more likely to get infections. When your body feels it is under attack, it makes special proteins called immunoglobulins or antibodies.

2023年10月24日 · IgG levels increase with age, with normal levels ranging from 700-1600 mg/dL in adults. Infants have lower levels. Learn what high and low levels mean.

2023年5月11日 · For patients with certain kinds of cancers, IgG levels may be affected by either the disease or the treatment, and replacement therapy is sometimes needed. What is IgG? Immunoglobulins are also known as “antibodies.” These immunoglobulins/antibodies are proteins made by B-cells, a type of white blood cell (WBC).

The IgG blood test is used to detect either a deficiency or an extra amount of immunoglobulins that are in the blood. This information gives medical providers an idea of a patient’s overall health in regards to their immune system.

Normal IgG levels vary based on age, sex, and overall health. Generally, healthy adults have normal serum IgG levels ranging from 700 to 1600 mg/dL (milligrams per deciliter). However, these values can fluctuate due to various factors such as genetics, underlying health conditions, and recent infections.

IgG (immunoglobin G) is the most abundant antibody in the blood. It helps prevent infections. When the body doesn't make enough IgG, it's called IgG deficiency. IgG is ready to attack when foreign substances get into the body. When you don't have enough IgG or it's not working correctly, you are more likely to get infections.
