What is a normal total IgE?
What is a normal total IgE?
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 causes very high IgE levels?
Elevated serum immunoglobulin E(IgE) can be caused by allergies, infections and immune conditions including hyper IgE syndrome (HIES).
What level of IgE is high?
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 if IgE is high?
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.
How is high IgE treated?
Omalizumab (Xolair®) is the anti-IgE medicine now available. Xolair is made to be similar to natural antibodies and is designed specifically to capture most of the IgE and block the allergic response.
How can I lower my IgE level?
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.
What is considered a high IgE level?
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 the reason for elevated IgE levels?
High IgE levels can be a sign of infection, allergic reaction, autoimmune disease or the presence of cancer. Low levels of IgE are hard to detect and usually are associated only with rare immunodeficiency diseases. Lindsay Nixon has been writing since 2007.
What does IgE mean in lab results?
An immunoglobulin E (IgE) test measures the level of IgE, a type of antibody. Antibodies are made by the immune system to protect the body from bacteria, viruses, and allergens. IgE antibodies are normally found in small amounts in the blood, but higher amounts can be a sign that the body overreacts to allergens.
What does my IgE level mean?
IgE is an antibody found in the blood that is a marker for allergy diseases. People who have elevated IgE levels can have environmental or food allergies. If you get a blood test and it shows that you have an elevated IgE that could mean you are an allergic patient.
What is the meaning of IgE?
Definition of IgE. 1 : a class of immunoglobulins including antibodies that function especially in allergic reactions. 2 : an antibody of the class IgE.
