Fruit Allergy Test
Fruit Allergy Test
This test measures a person's allergic reaction to several types of fruit. Fruit allergy can sometimes be caused by a condition known as oral allergy syndrome (OAS). People with an allergy to certain types of pollen may develop OAS due to similarities between pollen and the proteins found in some types of fruit. OAS can also cause allergic reactions to some types of vegetables and nuts. In some cases, people who are allergic to raw fruits may be able to eat the same types of fruit with no problem when they are cooked. This is because the proteins that trigger the allergic reaction break down when exposed to heat. Allergy symptoms can develop anywhere from a few minutes to a few hours after ingestion. Common symptoms include tingling in the mouth, hives, itching, rash, swelling of the lips, tongue, or throat, difficulty breathing, flushed skin, diarrhea, nausea, or vomiting. A severe allergic reaction can sometimes cause anaphylaxis which may be life-threatening.
This allergy panel includes testing for:
Allergies develop when the body's immune system identifies certain substances as harmful and produces IgE antibodies against them. These antibodies trigger the release of histamine which causes the symptoms of an allergic reaction. The severity of the allergy will vary from one person to the next. Blood allergy testing provides numerical results for IgE antibody levels to help determine how severe a reaction a person will have. Positive allergy test results should be discussed with a person's doctor to determine the appropriate follow up.
Allergy testing is typically ordered when a person experiences symptoms of an allergic reaction after eating a particular food. For more testing options, please see out Allergy Testing Category.
Results for this test typically take 3-5 business days.
