Quick Answer: What Are Normal IgM Levels?

What is a low IgM level?

Could this be a selective IgM deficiency.

Selective IgM deficiency is an isolated absence or profound deficiency of serum IgM associated with infections, atopic manifestations, autoimmunity, or malignant conditions.

Serum IgM levels are less than 10–15 mg/dl in infants and children and less than 20–30 mg/dl in adults..

What are IgM levels?

Immunoglobulin M: Your body makes IgM antibodies when you are first infected with new bacteria or other germs. They are your body’s first line of defense against infections. When your body senses an invader, your IgM level will rise for a short time.

What happens if immunoglobulin is high?

If your immunoglobulin levels are too high, it may be a sign of an autoimmune disease, a chronic illness, an infection, or a type of cancer. Symptoms of these conditions vary greatly.

What does high cardiolipin IgM mean?

The levels of these antibodies are often high in people with abnormal blood clotting, autoimmune diseases like systemic lupus erythematosus (SLE), or repeated miscarriages.

What causes anti M antibody?

Anti-M may be naturally occurring (i.e. arising without stimulus by transfusion or pregnancy related red blood cell exposure) or can be an immune stimulated antibody. In either case, it is predominantly an IgM antibody with some associated IgG component and often occurs in association with other antibodies.

What does an IgM blood test show?

Immunoglobulin M (IgM): Found mainly in blood and lymph fluid, this is the first antibody the body makes when it fights a new infection. Immunoglobulin E (IgE): Normally found in small amounts in the blood. There may be higher amounts when the body overreacts to allergens or is fighting an infection from a parasite.

What can cause low IgM?

Other causes of decreased levels of serum IgM (i.e., secondary IgM deficiency) are episodes of infection, thymic hypoplasia, celiac disease, autoimmune disease, and certain adult malignancies; and other PIDs (Wiskott-Aldrich syndrome, DOCK8 deficiency, ataxia-telangiectasia, CVID, and XLA, in combination with IgG and …

Which comes first IgG or IgM?

IgM antibody appears first, followed by IgA on mucosal surfaces or IgG in the serum. The IgG antibody is the major antibody of the response and is very stable, with a half-life of 7 to 21 days.

How do I test my immune system level?

Tests used to diagnose an immune disorder include: Blood tests. Blood tests can determine if you have normal levels of infection-fighting proteins (immunoglobulin) in your blood and measure the levels of blood cells and immune system cells. Abnormal numbers of certain cells can indicate an immune system defect.

What is considered a high M protein level?

High levels mean the disease is more advanced and may indicate a poor prognosis. The presence of any M spike is abnormal and shows the presence of an abnormal clone of plasma cells. If the amount of protein is ≥30 g/L and/or there are other disease symptoms, the patient may have myeloma.

What is normal range for IgM?

Normal Ranges Adult: IgG 6.0 – 16.0g/L. IgA 0.8 – 3.0g/L. IgM 0.4 – 2.5g/L.

What is a high IgM level?

IgM. High levels of IgM can mean macroglobulinemia, early viral hepatitis, mononucleosis, rheumatoid arthritis, kidney damage (nephrotic syndrome), or a parasite infection is present.

Is High IgM serious?

Patients with hyper IgM are at significant risk for opportunistic and repeated infections. In addition, the defect in the immune system results in a decreased ability to identify and fight cancer cells as well as an inability to produce a response to pathogens.

Is low IgM serious?

Selective IgM deficiency is more common than previously recognized and is likely a heterogeneous disorder. Patients with SIGMD may be asymptomatic; however, commonly present with chronic and recurrent infections; some of them could be serious and life threatening.

What is the function of IgM?

IgM is present on B cells and its main function apparently is the control of B-cell activation. B-cells create IgM antibodies as a first line of defense. Their large size gives them excellent binding avidity, and can pick up trace amounts of infection to mark for recognition by phagocytes.

What does IgM stand for?

Immunoglobulin M (IgM), which is found mainly in the blood and lymph fluid, is the first antibody to be made by the body to fight a new infection. Immunoglobulin E (IgE), which is associated mainly with allergic reactions (when the immune system overreacts to environmental antigens such as pollen or pet dander).

What is normal range for IgA?

immunoglobulin a normal range The IgA normal range differs with age and the IgA normal range for an healthy adult is between 80 – 350 mg/dL.
