Other labs set the cutoff higher: ARUP lists a reference interval of 0.34 kU/L or lower for Bermuda grass in its regional respiratory panels, 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, Grass, Bermuda (test 0055070)","url":"https://ltd.aruplab.com/Tests/Pub/0055070","publisher":"ARUP Laboratories"},{"title":"Allergen, Region 10 Respiratory Panel IgE, Southwestern Grasslands (test 3001720)","url":"https://ltd.aruplab.com/Tests/Pub/3001720","publisher":"ARUP Laboratories"},{"title":"Bermuda Grass (test 602464)","url":"https://www.labcorp.com/tests/602464/bermuda-grass","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.
