High IgG is a term used to describe an elevation of immunoglobulin G (IgG) in the blood. IgG is an antibody produced by the body's immune system and it plays an important role in fighting off infections. In general, IgG levels remain relatively constant, but can increase in response to an infection or allergic reaction.
High levels of IgG can be an indication of an active or recent infection. It can also be an indication of an autoimmune disorder, such as lupus or rheumatoid arthritis. High IgG levels can also indicate the presence of an allergy, such as to pollen or food.
High IgG levels can be detected through a blood test. Your doctor will look for increases in IgG levels and will investigate further if levels are abnormally high. Treatments for high IgG will depend on the underlying cause. If an infection is present, your doctor may prescribe antibiotics or antiviral drugs. If an autoimmune disorder is present, your doctor may recommend immunosuppressant drugs or other treatments. If an allergy is present, your doctor may recommend avoidance of the allergen or other treatments.
In conclusion, high IgG is a term used to describe an elevation of immunoglobulin G (IgG) in the blood. High IgG levels can be an indication of an infection, autoimmune disorder, or allergic reaction. A blood test can be used to detect high IgG levels. Treatment will depend on the underlying cause.
