What is a normal IgE test result?
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 normal IgE levels in adults?
Variations in the upper limit of normal total serum IgE have been reported: they can range from 150 to 1,000 UI/ml; but the usually accepted upper limit is between 150 and 300 UI/ml.
What IgE level is high?
Table. IgE level test ratings and interpretations
| Rating of specific IgE level (kUA/L) | Grade/Class | Interpretation |
|---|---|---|
| Low (0.35–0.69) | I | Doubtful significance |
| Moderate (0.70–3.49) | II | Possible |
| High (3.50–17.49) | III | More possible |
| Very high (17.50–49.99) | IV | More likely |
What is an abnormal IgE?
The hyper IgE syndromes (HIES) are rare primary immune deficiencies characterized by elevated serum IgE, rash and recurrent bacterial infections of the skin and lung.
What is a normal immunoglobulin level?
Normal Ranges Adult: IgG 6.0 – 16.0g/L. IgA 0.8 – 3.0g/L. IgM 0.4 – 2.5g/L.
What is high immunoglobulin?
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.
What is IgE level for asthma?
Mean IgE levels ranged from 151.95 IU/ml in normal subjects to 1045.32 IU/ml in severe asthmatics.
What is high IgA?
High IgA (>4g/L) elevated IgA levels are nonspecific, but can be seen in pulmonary and gastrointestinal inflammatory diseases, some autoimmune conditions, liver disease, and plasma cell disorders.
How do you reduce immunoglobulin E?
Several strategies for decreasing IgE have been developed as a possible treatment for asthma. For example, anti-IgE monoclonal antibodies such as rhuMAb-E25 and CGP 56901 block binding of IgE to its high-affinity receptor and have been shown to reduce IgE levels in humans without causing anaphylaxis.
Does high IgE mean asthma?
IgE (Immunoglobin E) are antibodies produced by the immune system. They can be elevated for many reasons. A common reason may include the presence of an allergic condition. Allergic conditions include atopic dermatitis, allergic rhinitis, asthma, and food allergy.
What is a low level of IgE?
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).
