A total IgE test result that is high means that you may have some kind of allergy. But the results of a total IgE test don’t show what you’re allergic to or how serious your allergy may be. A specific IgE test result that is high means that you may be allergic to the allergen that was tested.

What causes IgE levels to be high?
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 do I do if my IgE level is high?
Treatment
- Allergen avoidance. Your provider will help you take steps to identify and avoid your allergy triggers.
- Medications. Depending on your allergy, medications can help reduce your immune system reaction and ease symptoms.
- Immunotherapy.
- Emergency epinephrine.
What is normal range for IgE levels?
Normal IgE Levels
Normal values may vary in the scientific literature, but the usual reference range is 1.5-144 kU/L (IU/mL) [1, 23].
What kind of infection does IgE indicate?
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 are the symptoms of high IgE?
Hyper-IgE syndrome typically causes recurrent staphylococcal abscesses of the skin, lungs, joints, and viscera; sinopulmonary infections; pulmonary pneumatoceles; and a severe pruritic eosinophilic dermatitis. Patients have coarse facial features, delayed shedding of baby teeth, osteopenia, and recurrent fractures.
What diseases have 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, Sézary’s syndrome, IgE myeloma, and Kimura’s disease[1].
Can high IgE be cured?
Omalizumab is a recombinant humanized monoclonal antibody that binds IgE and has been used treat allergic asthma for over a decade. Currently, omalizumab is approved for the treatment of both allergic asthma and chronic spontaneous urticaria.
What foods to avoid if you have high IgE?
An IgE-mediated allergic reaction usually occurs within several hours of eating the food allergen and can include mild to severe symptoms, including anaphylaxis ( 8 ).
Here are the eight most common food allergies.
- Cow’s milk.
- Eggs.
- Tree nuts.
- Peanuts.
- Shellfish.
- Wheat.
- Soy.
- Fish.
What autoimmune disease causes high IgE levels?
Elevated total IgE levels are frequent in patients with autoimmune pancreatitis (21, 112), and it was recently suggested that analysis of total IgE in serum might be useful in the differentiation between autoimmune pancreatitis and pancreatic carcinoma (113).
How do I lower my IgE?
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 accurate is the IgE blood allergy test?
A positive SPT is reliable about 50 percent of the time, but a negative SPT result is about 95 percent predictive. By itself, the positive result just indicates that your body has made allergic antibodies, called IgE, to a specific food. This is called “sensitization,” and by itself is not enough for a diagnosis.
What is considered a high IgE level?
Abstract. 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.
Which doctor to consult if IgE is high?
Talk to experienced dermatologist online and get your health questions answered in just 5 minutes. Yes it is helpful. But you will need further tests to find out the cause of elevated Ig E levels. Pls consult a dermatologist near you for detailed allergy tests .
Can you have high IgE without allergies?
Increased IgE without other symptoms is likely of no clinical significance, although it is surprising that the value is increasing. There was no mention of eosinophilia. If eosinophilia were present, I would be more concerned about occult parasite disease such as echinococcal disease or schistosomiasis.
How long does IgE stay elevated?
In contrast to IgG antibodies, which have a half-life of about 3 weeks, IgE is very short-lived in plasma (half-life, <1 day), but receptor-bound IgE can remain fixed to mast cells in tissues for weeks or months.
How can I reduce my IgE naturally?
10 Eating Tips to Help You Minimize Allergy Symptoms
- Allergy and Asthma Symptom Relievers.
- Avoid Spicy Foods When Pollen Counts Are High.
- Don’t Eat Raw Foods at the Height of Allergy Season.
- Eat Yogurt and Other Probiotics.
- Stick to a Low-Salt Diet.
- Skip the Fast Food.
How long does it take for IgE levels to reduce?
Furthermore, analysis of previous data suggests that it takes time to significantly decrease the expression of the high affinity IgE receptors on either basophils (2 weeks) or mast cells (10 weeks); whereas a therapeutic effect within 1 week is noted in some patients (42, 43).
Do Antihistamines reduce IgE?
H1 antihistamines significantly improved TSS, with no differences between the investigated drugs. There was a significant decrease of eosinophils, total IgE, and FeNO after treatment. H1 antihistamines significantly decreased the plasmatic levels of ICAM-1 and E-selectin but not VCAM-1 compared to basal values.
Does high IgE mean asthma?
In a large study, high serum IgE was observed in children with severe asthma and in adults with early-onset asthma [96], whereas very high serum IgE (>2000 kU·L−1) also correlated with the severity of dermatitis [97].
How do you flush allergens out of your system?
Keep yourself hydrated. “While your body is purging the allergen food from it is system, the best thing you can do is drink plenty of fluids,” Zeitlin says. Water is always a good idea, but you can also sip on low calorie sports drinks to replenish the electrolytes you’re likely losing, Zeitlin says.
