How do you interpret IgE results?
How To Interpret Results
- Values under 0.35 mean unlikely sensitization to the allergen.
- Values between 0.35-0.69 mean doubtful significance.
- Values between 0.70-3.49 mean there is a possibility.
- Values between 3.50-17.49 mean a greater possibility.
- Values between 17.50-49.99 mean very likely.
What is considered a high total IgE level?
According to most labs, IgE levels above 150 kU/L are considered high.
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 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 does ImmunoCAP test for?
ImmunoCAP™ tests provide an objective measurement of the circulating allergen-specific IgE antibodies. Specific IgE antibodies appear as a result of exposure and following sensitization to an allergen.
What is IgE level in allergy?
An allergen-specific immunoglobulin E (IgE) test is a blood test that measures the levels of different IgE antibodies in a person’s blood. Allergen-specific IgE tests are sometimes used to diagnose and better manage food allergies. They can also be helpful for environmental allergy diagnosis in some cases.
What if IgE level is more than 1000?
Conditions associated with unusually high serum IgE concentrations (>1,000 IU/mL) are allergic bronchopulmonary aspergillosis, allergic fungal sinusitis, atopic dermatitis, human immunodeficiency virus infection, hyper IgE syndrome, IgE myeloma, lymphoma, systemic parasitosis and tuberculosis [4].
