Order Peanut Allergy Test | Legume/Nut AllergyA peanut allergy test measures the amount of peanut-specific immunoglobulin E (IgE) in the blood. IgE is the antibody class the immune system produces in response to allergens, and its presence at elevated levels can indicate sensitization to peanut proteins. Because peanuts are legumes, reactivity to peanut does not automatically imply reactivity to other legumes such as soy, lupin, or peas, and vice versa. This test is used to evaluate suspected peanut allergy when a clinician determines that blood testing is appropriate.
About Peanut Allergy Test | Legume/Nut Allergy in The Colony
Peanut allergy is an immune-mediated reaction to proteins found in Arachis hypogaea, the legume commonly known as the peanut.
Peanut proteins can trigger IgE-mediated responses that range from mild oral itching to urticaria, gastrointestinal symptoms, respiratory distress, and anaphylaxis. The severity of a reaction is not reliably predicted by the size of an IgE result alone, so blood testing is interpreted alongside clinical history and, when indicated, other diagnostic methods.
Peanut is a legume, but it is botanically distinct from tree nuts such as almond, cashew, and walnut. Cross-reactivity between peanut and tree nuts is possible but not universal, and many individuals with peanut allergy tolerate tree nuts. Similarly, sensitization to one legume does not guarantee sensitization to another, which is why legume panels are ordered selectively rather than reflexively.
This test detects peanut-specific IgE in a blood sample. Results are reported as a quantitative value, often in kilounits of allergen-specific IgE per liter, and are classified as negative, equivocal, or positive according to the laboratory's reference range. A positive result confirms sensitization but not necessarily clinical allergy; a negative result makes IgE-mediated peanut allergy less likely but does not exclude it entirely.
