ARUP Laboratories prints a result under 0.10 kU/L as class 0, which it describes as no significant level, 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. ARUP lists 0.10 to 0.34 kU/L as clinical relevance undetermined and says those results are for specialist use. Mayo Clinic Laboratories also prints a result under 0.10 kU/L as class 0 (negative) and flags 0.70 kU/L and above as high. The ImmunoCAP maker recommends a 0.35 kUA/L cutoff and tells each lab to set its own range, and its FDA review gives the expected value as under 0.35 kUA/L in people without a tendency to allergies. 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":"Allergen, Tree, Sycamore Tree (ARUP test 0055090)","url":"https://ltd.aruplab.com/Tests/Pub/0055090","publisher":"ARUP Laboratories"},{"title":"Eastern Sycamore, IgE, Serum (test ID ESYC)","url":"https://www.mayocliniclabs.com/test-catalog/overview/82721","publisher":"Mayo Clinic 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"}]}],"review":{"status":"ai-verified","label":"AI-verified against cited sources.
