How do you test your immune system?

Since most of your immune ‘security guards’ live in your blood and bone marrow, a blood test is the primary way to check if your immune system is deficient. A Complete Blood Count (CBC) Lab Draw evaluates your numbers of white blood cells and antibodies to determine if your levels are cause for concern.

What are the five classes of immunoglobulin?

There are five main classes of heavy chain C domains. Each class defines the IgM, IgG, IgA, IgD, and IgE isotypes. IgG can be split into four subclasses, IgG1, IgG2, IgG3, and IgG4, each with its own biologic properties; and IgA can similarly be split into IgA1 and IgA2.

What classes of immunoglobulins are most abundant in the body?

IgG. IgG is the most common class of immunoglobulin. It is present in the largest amounts in blood and tissue fluids.

What happens when IgG is high?

High levels of IgG may mean a long-term (chronic) infection, such as HIV, is present. Levels of IgG also get higher in IgG multiple myeloma, long-term hepatitis, and multiple sclerosis (MS).

Does IgG deficiency cause fatigue?

Background. Fatigue, sleep disturbance and altered mood are frequently reported in patients with primary antibody deficiency syndrome (PADS) on adequate immunoglobulin replacement therapy. This study aimed to determine the frequency of symptoms compatible with chronic fatigue syndrome (CFS) in patients with PADS.

How do you treat a positive IgG?

Currently, the accepted therapy for IgG deficiency is the intravenous administration of 300-600 mg/kg of IgG once every 3-4 weeks, or 100-200 mg/kg/wk subcutaneously. Higher doses have been shown to be more effective in reducing infections in patients with histories of chronic or recurrent sinopulmonary infections.

How can I lower my IgG levels?

Since hypergammaglobulinemia is caused by other conditions, there aren’t many direct treatment options available. But you can improve or cure this condition by treating other underlying infections, immune disorders, and diseases. One uncommon treatment for this condition is immunoglobulin replacement therapy.

What are the 5 major classes of immunoglobulins?

The five primary classes of immunoglobulins are IgG, IgM, IgA, IgD and IgE. These are distinguished by the type of heavy chain found in the molecule. IgG molecules have heavy chains known as gamma-chains; IgMs have mu-chains; IgAs have alpha-chains; IgEs have epsilon-chains; and IgDs have delta-chains.

What kind of doctor treats IgG deficiency?

Immunologists are scientists or doctors who specialize in diseases of the immune system. Immunologist physicians may manage the treatment of patients with primary immunodeficiency disease. Infectious disease specialists are also frequently involved in the care of these patients.
