Description

Order an apple allergy IgE blood test to detect an allergy to apples. This test measures the amount of allergen-specific antibodies in a blood sample. Apples are one of the most widely grown and consumed fruits, and they are farmed to be eaten fresh, used as an ingredient for cooking, and in the manufacturing of apple juice or cider. There are several varieties of apples to choose from, each with its own texture and color.

When the fruit matures and is harvested, apple varieties are categorized into two groups: summer and late autumn. They grow in temperate settings and ripen immediately after being cut from the tree. Apples can be preserved in controlled environment chambers for up to several months, delaying the onset of ripening.

The amount of allergenic protein in apples has been found to vary depending on the ripeness of the particular fruit and the variety, with apples that have matured or been stored for extended periods of time having a greater allergen load.

An allergy to apples triggers a reaction in an individual's immune system. The body views certain substances as toxic and produces IgE antibodies to these contaminants. These antibodies cause histamine to be released, which will cause the symptoms of an allergic reaction.

Allergy symptoms vary from one individual to the next ranging from mild to severe reactions, which can be experienced within minutes to hours after exposure. Common symptoms of an apple allergy may include one or more of the following symptoms:

  • Hives
  • Tingling in mouth
  • Swollen face, tongue, lips, or throat
  • Abdominal pain
  • Vomiting
  • Diarrhea
  • Nausea
  • Wheezing
  • Difficulty swallowing
  • In rare cases, anaphylaxis
