What is the purpose of this test?

Order this Allergen Profile, Vegetable I Blood Test measures the IgE antibody levels in the blood to detect an allergy to several common vegetables. A vegetable allergy falls under the umbrella of food allergies, which occur when the immune system mistakenly perceives a particular food as a harmful substance. As a result, the immune system releases histamine and other chemicals, causing allergic symptoms. The symptoms of a vegetable allergy can vary depending on the individual and the specific vegetable involved. It is important to identify the specific vegetable causing the allergy in order to avoid it and prevent further allergic reactions. 


Vegetable allergy symptoms could be due to:


  • Pollen food syndrome - Pollen food syndrome is an allergy that affects people with hay fever who are allergic to pollens. It causes allergic reactions when certain vegetables or fruits are consumed due to the similarity in proteins with pollen. Symptoms are generally mild and can be treated with antihistamines.
  • Allergy to lipid-transfer proteins (LTPs) - Lipid-transfer proteins (LTPs) are found in plants and can cause an allergy called Lipid Transfer Protein Syndrome. This syndrome can cause severe reactions to vegetables, fruits, nuts, and cereals in sensitized individuals.
  • Food intolerance - Food intolerance and food allergy are different conditions. A reaction of the immune system causes food allergy, while food intolerance may have a different cause. Intolerance to vegetables could be part of a wider intolerance to foods caused by a sensitivity to chemicals or an inability to digest sugars. Food intolerance can have a wider range of symptoms.
  • Sensitivity to chemicals in vegetables - Some people may be sensitive to chemicals naturally found in certain foods, such as salicylates. This can cause symptoms but is not an allergy. Salicylates are found in the skins of some vegetables and fruits, as well as tea, spices, honey, ginger, some drinks, and aspirin. These chemicals can cause wheezing or hives.


When should I order an Allergen Profile, Vegetable I Blood Test?

Individuals may order this test if they have experienced symptoms related to a vegetable allergy. Allergy symptoms vary depending on the individual, ranging from mild to severe reactions. Most food-related symptoms occur within two hours of ingestion but frequently begin within minutes. In addition, the response can be delayed by four to six hours or even longer in some rare cases.


An allergic reaction may affect the skin, intestinal lining, and air pathways. Individuals with a vegetable allergy may experience one or more of the following symptoms:


  • Tingling sensation near or around the mouth
  • Swelling
  • Abdominal discomfort
  • Nausea or vomiting
  • Diarrhea
  • Itching or hives
  • Congestion
  • Difficulty breathing, swallowing, or wheezing
  • Lightheadedness


In some cases, a severe, possibly life-threatening allergic reaction known as anaphylaxis may occur. An anaphylactic response requires immediate medical attention. Signs or symptoms of anaphylaxis may include:


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