Cranberry IgE Allergy Test in Idaho

What this test measures

This test detects allergen-specific immunoglobulin E against cranberry proteins. Berry allergies are uncommon but recognized, and they can cause oral itching, hives, digestive discomfort, or more serious reactions. Cranberries are often consumed in processed forms that also contain other ingredients, so identifying the true trigger can be difficult. The immunoassay reports a quantitative antibody level and an IgE class for cranberry.

A blood sample is collected by venipuncture at a partner laboratory and analyzed with an immunoassay. Results are reported in kilounits per liter, and total IgE or eosinophil counts may be included as supporting context. Because cranberry belongs to the same plant family as blueberry and bilberry, cross-reactivity is possible, and broader berry or fruit panels can help clarify the pattern when several foods are suspected.

People order this test after noticing symptoms linked to cranberry products, or when an elimination diet points toward berries. It may also be part of a wider food allergy evaluation. The test shows sensitization rather than a confirmed clinical allergy, so a qualified healthcare provider should interpret the result and guide any dietary decisions.
