Order this Green Bean Allergy test to measure the IgE antibody levels in a blood sample to detect an allergy to green beans. Green beans are a type of bean of the Fabaceae (Legume) family with origins in Central and South America. There are a variety of green beans, such as common bean, French bean, string bean, snap bean, wax bean, and haricot bean. Green beans are one of the top processed vegetables worldwide, with the United States as the leading producer.
Green beans are a rich source of fiber, vitamin C, folate, calcium, and iron. Due to their several health benefits, green beans are a significant part of many Americans' daily diet. Green beans may be prepared and eaten in several ways, such as:
- Steamed
- Boiled
- Roasted
- Canned
- Pickled
- Served in a soup or stew
An allergy to legumes like green beans is relatively common, with several of the most common allergenic foods in this family. Therefore, individuals allergic to green beans may also be sensitive to other legumes like lentils, soybeans, chickpeas, peanuts, and other beans. The key allergen in green beans is the lipid transfer protein (LTP) called Pha v 3. This allergen activates a response in an individual's immune system upon consumption of green beans, producing IgE antibodies that combat the foreign substance. The antibodies cause the chemical histamine to be released, triggering the symptoms associated with an allergic reaction.
Allergic reactions 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 green beans 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, possibly 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 include:
- Rapid or increased pulse
- Swollen throat or lump making it difficult to breathe
- Low blood pressure
- Extreme dizziness or loss of consciousness
