Other labs set the cutoff higher: ARUP lists a reference interval of 0.34 kU/L or lower for this test in its ABPA panel, calls 0.10 to 0.34 'clinical relevance undetermined', and says results in that range are for specialist use. Children's Minnesota Laboratory reports anything under 0.35 kU/L as negative. Thermo Fisher, which makes the ImmunoCAP system, says results of 0.1 kUA/L or more show sensitization, which is not the same as allergy. Results from different labs or test brands are not directly comparable.","sources":[{"title":"Allergen, Fungi and Molds, Aspergillus fumigatus (test 0055061)","url":"https://ltd.aruplab.com/Tests/Pub/0055061","publisher":"ARUP Laboratories"},{"title":"Allergic Bronchopulmonary Aspergillosis (ABPA) Panel (test 2004243)","url":"https://ltd.aruplab.com/Tests/Pub/2004243","publisher":"ARUP Laboratories"},{"title":"Aspergillus fumigatus Antibody, IgE (test 602471)","url":"https://www.labcorp.com/tests/602471/aspergillus-fumigatus-antibody-ige","publisher":"Labcorp"},{"title":"Allergen IgE (laboratory test information)","url":"https://www.childrensmn.org/Manuals/Lab/chemistry/allergen-ige.pdf","publisher":"Children's Minnesota Laboratory"},{"title":"Your quick guide to using ImmunoCAP Specific IgE testing","url":"https://corporate.thermofisher.com/content/dam/phadia/library/en/Quick_guide_to_using_ImmunoCAP_Specific_IgE_testing.pdf","publisher":"Thermo Fisher Scientific (Phadia)","year":2024},{"title":"Allergy Testing in Childhood: Using Allergen-Specific IgE Tests (clinical report)","url":"https://doi.org/10.1542/peds.2011-2382","publisher":"American Academy of Pediatrics (Pediatrics)","year":2012},{"title":"Sample report 607120, Allergens with Component Reflexes Area 20 (class description table)","url":"https://files.labcorp.com/testmenu-d8/sample_reports/607120.pdf","publisher":"Labcorp"}]}],"review":{"status":"ai-verified","label":"AI-verified against cited sources.
