What is the purpose of this test?
Order this Berry Allergy IgE, Blood Test Panel, which measures the IgE antibody levels in the blood to help detect an allergy to various berries. Strawberries and raspberries belong to the Rosaceae family, which consists of several flowering vines that produce fruits. Other fruits in the Rosaceae family include peaches, apples, and cherries. Blueberries belong to the Ericaceae family, which consists mainly of herbs and shrubs. However, this family also produces other fruits, such as cranberries and huckleberries.

Unfortunately, some hypersensitive individuals experience allergic reactions after ingesting certain berries. Food allergies are prevalent in the United States, affecting approximately 5% of adults and 8% of children. Adverse food reactions can lead to severe symptoms and chronic health conditions.
What causes an allergy to berries?
Allergic reactions to berries are generally associated with oral allergy syndrome (OAS) or pollen-food allergy. OAS is caused by cross-reactivity to allergens in pollen and raw fruits, vegetables, or some tree nuts. The immune system views pollen and specific proteins found in food as harmful and produce IgE antibodies to combat them. Unfortunately, these antibodies cause a chemical called histamine to be released in the blood, which prompts an allergic reaction.
When should I order a Berry Allergy IgE Blood Test Panel?
