Description

This test measures the IgE antibody levels in a blood sample to detect an allergy to peas. Peas are a type of legume of the Fabaceae family with origins in the Middle East. There are various peas, such as garden peas, snow peas, and snap peas. Other legumes in this family include lentils, soybeans, chickpeas, peanuts, and different types of beans. Peas are the top processed vegetable in the UK and the United States. Peas are rich in fiber and protein and contain vast amounts of vitamins, folate, manganese, iron, zinc, and magnesium. Peas are a common ingredient in many canned soups and stews and certain premade salads. Peas are also dried or roasted and eaten as a snack.

A pea allergy is uncommon; however, hypersensitive people who ingest peas or pea-based products may experience mild to moderate allergic symptoms. The key allergens in peas are the vicilin protein Pis s 1, the convicilin protein Pis s 2, and the lipid transfer protein (LTP) called Pis s 3a. These allergens activate an unnecessary response in an individual's immune system. As a result, the body views this allergen as harmful and produces IgE antibodies to combat the invader. Unfortunately, these antibodies cause histamine to be released, which causes an allergic reaction.

An allergic reaction may range from mild or moderate to severe and vary for each individual. An individual may experience allergic reaction minutes to a few hours after exposure to an allergen. An individual allergic to peas 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, life-threatening allergic reaction known as an anaphylactic shock can occur in the most severe cases. An anaphylactic response requires immediate medical attention. Signs of an anaphylactic shock include:

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