Mayo Clinic Laboratories and ARUP print a result under 0.10 kU/L as class 0 (negative), so the usual range here ends at 0.09 and a printed 0.10 counts as above it. Labs draw the line in different places. Mayo Clinic Laboratories lists 0.10 to 0.34 kU/L as borderline, 0.35 to 0.69 as equivocal, and flags 0.70 and above as high; its reference values apply to all ages. ARUP prints a reference interval of 0.34 kU/L or lower and says results of 0.10 to 0.34 are for specialist use because their meaning is unclear. The ImmunoCAP maker recommends a 0.35 kUA/L cutoff and tells each lab to set its own range. A result above these lines shows sensitization, which is not the same as an allergy. Use the range printed on your own lab report.","sources":[{"title":"Egg White, IgE, Serum (test ID EGG)","url":"https://www.mayocliniclabs.com/test-catalog/overview/82872","publisher":"Mayo Clinic Laboratories"},{"title":"Allergen, Food, Egg White (ARUP test 0055013)","url":"https://ltd.aruplab.com/Tests/Pub/0055013","publisher":"ARUP Laboratories"},{"title":"ImmunoCAP Specific IgE (allergen component f447) 510(k) decision memorandum K173726","url":"https://www.accessdata.fda.gov/cdrh_docs/reviews/K173726.pdf","publisher":"U.S. Food and Drug Administration"},{"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}]}],"review":{"status":"ai-verified","label":"AI-verified against cited sources.
