Order Grapefruit Allergy Test | Citrus AllergiesA grapefruit allergy test measures the presence of specific immunoglobulin E (IgE) antibodies in the blood that react to grapefruit proteins. This type of test is used when a person reports symptoms after eating or handling grapefruit or other citrus fruits, and a clinician wants objective evidence of sensitization.
About Grapefruit Allergy Test | Citrus Allergies in Pacifica
IgE antibodies are part of the immune system's response to normally harmless substances. When a person is sensitized to grapefruit, the immune system produces IgE that recognizes proteins in the fruit.
During an allergic reaction, IgE antibodies bind to mast cells and basophils. When grapefruit proteins cross-link these antibodies, the cells release histamine and other mediators, which produce symptoms such as itching, hives, swelling, or in more severe cases, breathing difficulty.
A blood test for grapefruit-specific IgE detects the amount of antibody directed against grapefruit allergens. Results are typically reported as a numerical value with a reference range. A detectable level indicates sensitization, but sensitization does not always mean a clinical allergy; symptoms must be interpreted alongside the test result.
Citrus allergies can involve grapefruit, orange, lemon, lime, and other related fruits. Because proteins in these fruits can be similar, a clinician may order additional tests to clarify which citrus fruits are relevant. The test itself requires a blood draw, and results are usually available within a few business days.
