Note: Result turnaround times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.

Special Instructions: It is suggested that you maintain your usual dietary habits and consume a variety of foods when possible within a couple weeks prior to blood collection, unless advised otherwise by your healthcare practitioner. Avoid eating foods that may have potentially resulted in a previous adverse reaction and/or anaphylaxis, as secondary exposure may prove fatal. Do not perform this test if you are taking blood thinning medications or if you have a blood clotting disorder unless authorized by your healthcare practitioner.

Immunosuppressive drugs such as oral and intranasal corticosteroids (e.g. prednisone, beclomethasone, fluticasone, triamcinolone) and topical cortisone suspensions and creams, in addition to immune-modulating drugs, may affect test results for antibody assessment.

Total IgE measurement is unavailable for patients under 10 years of age.

Description: An IgE mediated allergic reaction is known as Type 1, or immediate hypersensitivity. Symptoms typically occur soon after exposure to the allergen, and range from mild to severe - they can even be life-threatening.

US BioTek runs all IgE panels on a sophisticated FDA-approved immunoassay analyzer that utilizes enzyme-amplified chemiluminescence technology. Chemiluminescence provides lower detection limits than conventional ELISA, making it particularly suitable for IgE detection, which can be hard to detect due to its short half-life compared to other immunoglobulins.

The 44-Food panel assesses IgE response to 44 foods, carefully selected for their potential reactivity and their relevance to modern diets.
