This test measures the amount of IgE allergen-specific antibodies in a blood sample to detect an allergy to asparagus.
Asparagus is a vegetable produced universally. Along with garlic, onions, and leeks, it belongs to the Alliaceae or Lily family, which includes ferns, vegetables, and flowers such as tulips. The Asparagus subfamily consists of approximately 300 species. Each species contains a lipid transfer protein (LTP) called Aspa o 1, the critical allergen that causes asparagus allergy.
An allergy to asparagus activates a reaction in an individual's immune system. The body views certain substances as harmful and produces IgE antibodies to combat these invaders. 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 asparagus 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
