• Powering Tree Nut Allergy Insights With ImmunoCAP™

    Information provided by Quest Diagnostics


    For a child with tree nut allergies, the risks are everywhere. While most kids have no trouble recognizing Brazil nuts, almonds, cashews, or pistachios in a snack bowl, those same nuts are commonly found in cookies, candies, granola, or energy bars where they can be harder to spot. In addition, tree nut oils can also be present in everyday items such as lotions, hair care products, and soap, and can cause an allergic reaction even in those trace amounts.1

    People rarely outgrow tree nut allergies, so it is important to diagnose these allergies in a timely and accurate manner whenever suspected in patients of any age.

    Protecting your patients starts with the right diagnosis2

    For physicians, parents, and children, preventing an allergic reaction starts with knowing whether you are at risk. Given all the avenues for possible exposure outlined above, tree nut or tree nut oil reactions should be suspected any time an otherwise healthy child or adult presents with congestion, trouble swallowing, itching/rash, diarrhea, or abdominal cramps.3

    A faster and simpler way to test for tree nut allergies

    Quest’s ImmunoCAP tree nut component test directly measures immunoglobulin E (IgE) antibody levels for specific tree nuts using a simple blood draw. Unlike with traditional skin prick testing (SPT), patients do not have to taper antihistamines or other common medicines. There is no need to sit and wait for a skin reaction, and the ImmunoCAP test delivers a specific quantitative value in place of subjective SPT comparison cards.

    As most tree nut allergies are diagnosed in children 2 years old and younger, Quest’s ImmunoCAP test offers the advantage of being easier and less stressful for the young patient and their parent, and it can be used even when a severe rash is present.
