Testing uses ImmunoCAP specific IgE, the method most allergy research relies on.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003eIt also builds in automatic reflex to component testing. When a whole-allergen result comes back elevated, the lab runs the protein-level component tests for that allergen on the same sample, at no extra draw. That layer matters because a positive whole-allergen result on its own does not always mean a true clinical allergy. Component resolution helps separate genuine allergy from cross-reactive sensitization, giving you a clearer read on the real-world risk of a systemic reaction.\u003c\/p\u003e\n\u003cp
