What is normal range for IgE levels?

What is normal range for IgE levels?

Normal IgE Levels IgE has the lowest concentration of all antibodies, especially in people without allergies. Normal values may vary in the scientific literature, but the usual reference range is 1.5-144 kU/L (IU/mL) [1, 23].

What is an abnormal IgE?

Hyper IgE Syndrome (HIES) is a rare primary immunodeficiency disease characterized by eczema, recurrent staphylococcal skin abscesses, recurrent lung infections, eosinophilia (a high number of eosinophils in the blood) and high serum levels of IgE.

What is considered a high IgE level IU ml?

Normal mean IgE levels for the total sample were 32 IU/ml with highest levels (mean of 51 IU/ml) in school-age children. The highest IgE levels were found in patients with both asthma and eczema (mean of 985 IU/ml), followed by asthma alone (305 IU/ml), eczema alone (273 IU/ml), and allergic rhinitis (171 IU/ml).

What is considered a low IgE level?

Deficiency or low IgE is defined by an IgE concentration of less than 2.5 IU/ml thus the level mentioned would meet this definition. There is no specific immunodeficiency identified by isolated IgE deficiency and selective IgE deficiency is not included in the classification of primary immunodeficiency diseases (1).

What is a high IgE result?

The blood usually has small amounts of IgE antibodies. Higher amounts can be a sign that the body overreacts to allergens, which can lead to an allergic reaction. IgE levels can also be high when the body is fighting an infection from a parasite and from some immune system conditions.

What diseases cause high IgE?

Elevated levels of total serum IgE are associated with many diseases, including allergic bronchopulmonary aspergillosis (ABPA), parasitosis, atopic dermatitis, adult HIV infection, hyper-IgE (Job’s) syndrome, S├ęzary’s syndrome, IgE myeloma, and Kimura’s disease[1].

What causes elevated IgE?

The Memorial Sloan Kettering Cancer Center states that in rare cases, high levels of IgE are caused by IgE multiple myeloma, a bone marrow cancer that stems from plasma cells.

What causes high IgE levels?

What could cause high IgE levels? Genetics: The tendency to make more ige in response to foreign substances that enter the body (aka allergens) is inherited. Allergies and parastic infections are the common reasons why people develop high ige levels.

What type of allergy tests are most accurate?

Skin testing (prick/puncture and intradermal) and RAST (radioallorsorbent) testing are the only truly reliable tests for allergies and these need to be performed by an allergist who is not only trained in performing the test but in interpreting the results as well.

What exactly do they do in an allergy test?

During allergy skin tests, your skin is exposed to suspected allergy-causing substances (allergens) and is then observed for signs of an allergic reaction. Along with your medical history, allergy tests may be able to confirm whether a particular substance you touch, breathe or eat is causing symptoms.
