What is the purpose of this test?

Order this Tree Nut & Peanut Allergy Blood Test to measure the IgE antibody levels in the blood to screen for an allergy to certain tree nuts and peanuts. Nuts are a common food allergen in the United States, making up 1.8% of food allergy cases. Although peanuts are not classified as nuts (they are legumes), they contain similar proteins to tree nuts. Therefore, individuals allergic to peanuts may also be allergic to tree nuts, such as almonds, Brazil Nuts, pecans, walnuts, hazelnuts, and cashews. Most food allergies develop in childhood. Some individuals outgrow them over time, but many suffer from lifelong allergies, especially to tree nuts and peanuts. 

 

Consuming tree nuts or peanuts may activate an individual's immune system response. The key allergen in both tree nuts and peanuts is the protein: Ara h 2. Once ingested, the immune system will view these proteins as harmful and produce antibodies to combat these invaders. Unfortunately, these antibodies cause a chemical known as histamine to be released, triggering an allergic reaction.
