Description

What is the purpose of this test?

Order this Avocados Allergy IgE Blood Test to measure the IgE antibody levels in the blood and to help detect an allergy to avocados. Avocados are becoming increasingly popular, meaning more people include them in their daily recipes. Greater exposure to food or substance increases the risk of developing an allergy. It may not be as widespread as peanut or shellfish allergies, but an individual can have an allergy to avocados just the same.

There are two types of avocado allergy. First is an oral allergy caused by oral allergy syndrome. If an individual has an allergy to birch pollen, it is highly possible to have an oral allergy to avocados. Fruits and vegetables growing close to pollen can cause an allergic reaction in individuals sensitive to pollen. The second allergy is due to cross-reactivity with latex, otherwise known as latex-fruit syndrome. An individual with a latex allergy is more likely to react to avocados. This cross-reactivity means that both avocados and latex contain similar proteins.

Additionally, individuals that have a latex allergy may also be allergic to the following latex fruits:

• Kiwis
• Papayas
• Bananas
• Chestnuts

What causes an allergy to avocados?

An allergy to avocados is triggered by a reaction in an individual's immune system. The body views certain substances (proteins) as toxic and produces IgE antibodies to combat these contaminants. These antibodies cause histamine to be released, which will cause the symptoms of an allergic reaction.
