Mayo Clinic Laboratories lists 0.10 to 0.34 kU/L as borderline or equivocal and flags 0.70 and above, with the same values at all ages. ARUP Laboratories calls 0.10 to 0.34 kU/L 'clinical relevance undetermined' and says those results are intended for specialist use. The ImmunoCAP maker suggests a 0.35 kUA/L cutoff and tells each lab to set its own range. A result above these lines means sensitization, which is not the same as an allergy. Pollen from related trees such as ash, privet and lilac shares proteins with olive pollen (Pajaron 1997), so a raised result does not always mean olive trees are the cause. Results from different labs or test brands are not directly comparable.","sources":[{"title":"Allergen, Tree, Olive Tree (ARUP test 0055155)","url":"https://ltd.aruplab.com/Tests/Pub/0055155","publisher":"ARUP Laboratories"},{"title":"Olive Tree, IgE, Serum (test ID OLIV)","url":"https://www.mayocliniclabs.com/test-catalog/overview/82733","publisher":"Mayo Clinic Laboratories"},{"title":"510(k) Decision Memorandum K173726: ImmunoCAP Specific IgE (ImmunoCAP Allergen f447, rAra h 6, Peanut)","url":"https://www.accessdata.fda.gov/cdrh_docs/reviews/K173726.pdf","publisher":"U.S. Food and Drug Administration","year":2018},{"title":"Guidelines for the diagnosis and management of food allergy in the United States: report of the NIAID-sponsored expert panel","url":"https://pmc.ncbi.nlm.nih.gov/articles/PMC4241964/","publisher":"Journal of Allergy and Clinical Immunology","year":2010},{"title":"The spectrum of olive pollen allergens","url":"https://pubmed.ncbi.nlm.nih.gov/11490150/","publisher":"International Archives of Allergy and Immunology","year":2001},{"title":"Cross-reactivity of Olea europaea with other Oleaceae species in allergic rhinitis and bronchial asthma","url":"https://pubmed.ncbi.nlm.nih.gov/9284982/","publisher":"Allergy","year":1997},{"title":"Analysis of hypersensitivity to oleaceae pollen in an olive-free and ash-free area by commercial pollen extracts and recombinant allergens","url":"https://pubmed.ncbi.nlm.nih.gov/21789968/","publisher":"European Annals of Allergy and Clinical Immunology","year":2011},{"title":"Allergy to Cypress and Olive Pollen: Clinical Phenotypes and Allergen Recognition","url":"https://pubmed.ncbi.nlm.nih.gov/37539856/","publisher":"Journal of Investigational Allergology and Clinical Immunology","year":2024},{"title":"Allergy Blood Test","url":"https://medlineplus.gov/lab-tests/allergy-blood-test/","publisher":"MedlinePlus, National Library of Medicine"}]}],"review":{"status":"ai-verified","label":"AI-verified against cited sources.
