When IgE is released, the reaction is immediate, from seconds to hours, and because IgE can be held in B-memory cells in your bone marrow, that reactivity can persist for years, even if you've avoided the trigger the whole time. This test measures your IgE response to specific foods and airborne allergens directly, so we can identify what's actually driving a reaction and remove it with confidence.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003eSigns a true allergy may be part of your picture\u003c\/h2\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eIn adults:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eRash or hives\u003c\/li\u003e\n\u003cli\u003eWheezing or shortness of breath\u003c\/li\u003e\n\u003cli\u003eSudden sneezing or coughing\u003c\/li\u003e\n\u003cli\u003eSwelling of the lips, mouth, or throat\u003c\/li\u003e\n\u003cli\u003eChest pain or dizziness\u003c\/li\u003e\n\u003cli\u003eAbdominal pain, diarrhoea, nausea, or vomiting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eIn children:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003eRectal bleeding\u003c\/li\u003e\n\u003cli\u003eConstipation\u003c\/li\u003e\n\u003cli\u003eColic\u003c\/li\u003e\n\u003cli\u003eEczema\u003c\/li\u003e\n\u003cli\u003eAsthma\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003eIf your symptoms look more like brain fog, bloating, joint pain, chronic fatigue, or skin issues that build up over time rather than react immediately, that pattern points to food sensitivity (IgG) rather than allergy (IgE), which is a different test.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003eWhy cross-reactivity matters\u003c\/h2\u003e\n\u003cp dir=\"ltr\"\u003eFood allergy testing works best alongside aeroallergen testing, because up to 60 percent of food reactions happen through cross-reactivity with pollen. Pollens share proteins with certain fruits and vegetables, so exposure during pollen season can trigger or worsen a reaction to foods that wouldn't otherwise cause a problem. Testing both together gives a clearer picture of what's actually behind your symptoms, not just which single food or pollen looks suspicious in isolation.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eFood allergy panels\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e44 IgE Food Panel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2 dir=\"ltr\"\u003eHow the test works\u003c\/h2\u003e\n\u003cp dir=\"ltr\"\u003eEach panel uses a quantitative ELISA analysis to detect IgE specific to each food or inhalant allergen tested. The critical component of each allergen is extracted so the antibody in your sample binds correctly, and results are validated against positive and negative controls before being read. Every sample is tested in duplicate to catch any discrepancies before your results are finalised.\u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003eSample collection\u003c\/h2\u003e\n\u003cp dir=\"ltr\"\u003eYou can test using either method, depending on what's easiest for you:\u003c\/p\u003e\n\u003cul dir=\"ltr\"\u003e\n\u003cli\u003e\n\u003cstrong\u003eDried blood spot:\u003c\/strong\u003e a simple finger prick onto a collection card.

Food sensitivity involves a different, typically delayed, immune response. If your symptoms show up right away, allergy testing is the better starting point. If they build up gradually, food sensitivity testing may be more useful.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eIf I'm getting a food allergy IgE panel, should I also add Total IgE?\u003c\/strong\u003e Total IgE gives a broader read on your overall IgE reactivity alongside the specific allergens tested in your panel, and can add useful context to your results.\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cstrong\u003eDoes my medication affect the sample collection?\u003c\/strong\u003e Let us know what you're currently taking before you collect your sample so we can flag anything relevant when your results are reviewed.\u003c\/p\u003e","brand":"nutranourish","offers":[{"title":"Food Allergy Testing (IgE)","offer_id":45150981914832,"sku":null,"price":880.0,"currency_code":"SGD","in_stock":true},{"title":"Food Allergy Testing (IgE) + Enviromental Allergy Test","offer_id":45150981947600,"sku":null,"price":1000.0,"currency_code":"SGD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/0703\/7648\/files\/img-1759947543836.jpg?v=1788575486","url":"https:\/\/nutranourish.shop\/products\/products-allergy-testing","provider":"Nutranourish","version":"1.0","type":"link"}
