Order Grapefruit Allergy Test | Citrus AllergiesA grapefruit allergy test measures the amount of immunoglobulin E (IgE) antibodies in the blood that react to grapefruit proteins.

About Grapefruit Allergy Test | Citrus Allergies in Staten Island
This test uses a blood sample to assess IgE-mediated sensitivity to grapefruit. It is typically ordered when a person reports symptoms after eating or handling citrus fruit and a clinician wants objective evidence to support or rule out an allergy.
IgE antibodies are part of the immune system's response to normally harmless substances. When a person is sensitized to grapefruit, these antibodies bind to specific proteins in the fruit and can trigger the release of histamine and other chemicals. That release is what produces symptoms such as itching, hives, swelling, or, in severe cases, anaphylaxis.
A blood-based IgE test offers a standardized way to look for this sensitization. The result is reported as a numerical value or class that reflects the level of grapefruit-specific IgE. Higher values generally indicate a greater likelihood of clinical allergy, but the number alone does not confirm a diagnosis; the clinician interprets it alongside the person's history and physical findings.
Citrus allergies are relatively uncommon, and some reactions to grapefruit are not true allergies. Certain compounds in grapefruit can cause irritation or interact with medications, and some people experience oral allergy syndrome linked to pollen. Distinguishing these possibilities is part of why testing is used selectively rather than as a routine screen.
