What does the IgE Antibodies to 15 Common Foods test measure?

Q: Why is IgE Antibodies to 15 Common Foods measured?

Specific IgE to foods is the serological cornerstone of IgE-mediated food allergy evaluation, alongside skin prick testing and oral food challenge. A positive IgE indicates sensitisation; clinical reactivity is confirmed by history and, when necessary, supervised challenge. The 15-food subset in this panel typically includes the most common triggers — milk, egg, peanut, tree nuts, soy, wheat, fish, and shellfish — making it a useful first-line screen in patients with suspected immediate allergy.

Q: What is the reference range for IgE Antibodies to 15 Common Foods?

The standard reference range for IgE Antibodies to 15 Common Foods is Class 0 (<0.35 kU/L) is negative; Class 1–6 represent increasing IgE levels, with Class 2 and above generally considered positive.. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

IgE Antibodies to 15 Common Foods (IgE) is a clinical biomarker used in food-sensitivity-allergy assessment. Immunoglobulin E mediates immediate-type hypersensitivity reactions. It is measured in 1 laboratory test on BiomarkersLabs.com.

Reference Range: Class 0 (<0.35 kU/L) is negative; Class 1–6 represent increasing IgE levels, with Class 2 and above generally considered positive.
Units: kU/L, Class 0–6
Measured In: 1 test
Category: Food Sensitivity

Functional medicine optimalClass 0 is optimal for foods that are tolerated. Higher classes correlate with increased likelihood of clinical reactivity, though predictive values vary by food and patient age.

What is IgE Antibodies to 15 Common Foods?

Immunoglobulin E mediates immediate-type hypersensitivity reactions. Food-specific IgE binds to mast cells and basophils; upon re-exposure to the allergen, cross-linking of IgE triggers degranulation and release of histamine and other mediators, producing symptoms within minutes to two hours. Sensitisation (detectable IgE) does not always equal clinical allergy — many individuals with positive IgE to a food tolerate it without symptoms.
