What is the purpose of this test?

Order this Orange Allergy IgE Blood Test, which measures the IgE antibody levels in the blood to help detect an allergy to oranges. Oranges belong to the Citrus family, which includes many flowering plants. Other fruits in the citrus family include grapefruit, limes, and lemons. Oranges are low in calories and are a good source of fiber, vitamins, and minerals. Oranges also help protect against heart disease, colon cancer, and obesity. Due to their many health benefits, oranges are an essential ingredient in many products, including:

 

  • Jams, preserves, purees
  • Beverages (smoothies and juices)
  • Frozen desserts
  • Herbal teas
  • Salads
  • Yogurts
  • Marinades, sauces, and dressings
  • Alcoholic and non-alcoholic cocktails
  • Candies and desserts
  • Wine

 

Unfortunately, some hypersensitive individuals experience allergic reactions after ingesting oranges. 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 oranges?

Allergic reactions to oranges 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 an Orange Allergy IgE Blood Test?

Individuals may order this panel if they experience an allergic reaction after ingesting oranges. An allergic reaction may vary from mild or moderate to severe and vary depending on the individual. Individuals may experience allergic reactions minutes to a few hours after exposure. An individual allergic to oranges may experience the following symptoms:

 

  • Tingling sensation in or around the mouth
  • Swelling 
  • Abdominal pain
  • Nausea or vomiting
  • Diarrhea
  • Itching, hives, or eczema
  • Congestion
  • Trouble breathing or wheezing
  • Lightheadedness

 

An extreme, a potentially life-threatening allergic reaction known as anaphylaxis can occur in the most severe cases. An anaphylactic response requires immediate medical attention. Signs or symptoms of anaphylaxis may include:

 

  • Rapid or increased pulse
  • Swollen throat or lump making it difficult to breathe
  • Low blood pressure
  • Extreme dizziness or loss of consciousness
