What is a normal range for 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 is a high IgE level?
An elevated level of total IgE indicates an allergic process is likely present, but it will not indicate what a person is allergic to. In general, the greater the number of things a person is allergic to, the higher the total IgE level may be.
What do IgE test results mean?
Allergy blood tests measure the amount of IgE antibodies in the blood. A small amount of IgE antibodies is normal. A larger amount of IgE may mean you have an allergy.
What is IgE level for asthma?
Results: This study indicated that mean serum IgE level was 554 +/- 447 IU/mL in asthmatic patients, while that of the control population was 69 +/- 33 IU/mL. There was no overlap in the values of 95% confidence interval (CI) of higher control limit and lower asthmatic limit values.
What is 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 normal 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 immune system conditions cause high IgE levels?
Increased IgE levels have also been reported in patients with systemic lupus erythematosus (SLE) and other autoimmune disease that are driven by the aberrant production of interferon and self-damaging autoantibodies.
What causes very high IgE levels?
Diseases which cause the elevation of serum IgE levels include atopic diseases (asthma, allergic rhinitis, atopic dermatitis, urticaria), parasitic diseases, cutaneous diseases, neoplastic diseases, and immune deficiencies [3].
What is the treatment of high IgE?
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 do I read my allergy blood test results?
The blood test will reveal what exactly you are allergic to. However, you can test positive for something but never have had an allergic reaction to it. A negative result means you probably do not have a true allergy. That means your immune system probably does not respond to the allergen tested.
How do you read allergy test results?
If there is no reaction with a wheal and flare, the test is read as negative and being allergic is very unlikely. If the skin test is positive, it implies that the patient has a type of antibody (IgE) on specialized cells in the skin that release histamine to cause symptoms of an allergic reaction.
Is IgE good or bad?
IgE is most commonly associated with allergic disease and thought to mediate an exaggerated and/or maladaptive immune response to antigens. Once antigen specific IgE has been produced, re-exposure of the host to that particular antigen results in the typical immediate hypersensitivity reaction.
Does high IgE mean asthma?
Symptoms Caused by Excess IgE Increased levels of IgE may contribute to symptoms of asthma, such as: Wheezing. Chest tightness. Shortness of breath.
Why is IgE elevated in asthma?
Most asthmatic patients have elevated circulating IgE concentrations when levels are adjusted for age [2]. Allergic sensitization results from the formation of specific IgE in response to common inhalant allergens, such as those derived from house dust mites, pollens, animal dander, molds, and cockroaches.
How does IgE work in asthma?
Allergen-specific IgE also supports antigen presentation by facilitating antigen uptake by B cells (mediated by CD23) and DCs. Cutaneous DCs (ie, Langerhans’ cells) express FcRI, and allergen sensitization through the skin has been shown to induce bronchial sensitivity and inflammatory responses on challenge.
What does .10 mean on an allergy test?
< 0.10. Absent or Undetectable Individual/Component Allergen(s) 0. 0.10 0.34. Very Low for Individual/Component Allergen(s)
What causes IgE deficiency?
Recent genetic studies report that the cause of the IgE deficiency is immune dysregulation caused by polymorphisms of the gene, which is responsible for the synthesis of activation-induced cytidinedeaminase (AICDA).
How do you convert IU ml to KU L?
The Unit KU/L=KIU/L=1000 IU/L=IU/ml.
What are IgE levels?
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.
Is IgE high in autoimmune disease?
High levels of IgE antibodies are being found in other autoimmune diseases, such as lupus, and IgE is becoming increasingly associated with severe disease, he said.
Is IgE elevated in lupus?
RATIONALE: Elevated serum IgE concentrations have sometimes been found in systemic lupus erythematosus (SLE) patients. Reasons for these findings and associations with clinical and autoantibody phenotype remain controversial.
Is IgE an inflammatory marker?
Immunoglobulin E is a key mediator of the inflammatory reactions that are central to the pathogenesis of respiratory diseases such as Asthma. There is evidence that IgE plays a central role in allergic responses to allergens in asthma and rhinitis patients (Bousquet et al., 2006).
How can I get my IgE levels down?
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.
How do you treat high IgE levels naturally?

Can stress cause high IgE levels?
Higher stress between ages 6 and 18 months was associated with a high total IgE level (OR, 2.03; 95% CI, 1.1-3.6). Higher stress was significantly associated with increased production of TNF-, with a suggested trend between higher stress and reduced INF- production.
Do IgE allergies go away?
Higher IgE blood levels usually means they are less likely to outgrow their food allergy. Once diagnosed, the skin prick test size and the severity of the original reaction are not as helpful to predict if a child will outgrow their food allergy. These tests are best performed and interpreted by an allergy specialist.
What foods increase IgE?
Specific IgE levels were highest for peanuts, followed by cow’s milk, eggs, soy, and almonds, and trended upward over time. Conclusion: In children presenting with clinical symptoms of a reaction to a food allergen, measurements of food-specific serum IgE to other common food allergens are commonly positive.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
