Test Purpose:
Measures IgE antibodies in the blood to detect allergies to specific legumes, including peanuts, soybeans, and lentils.
Legumes Included:
- Peanuts: One of the most common allergens in the U.S.
- Soybeans: Frequently found in various food products, including vegetarian and vegan options.
- Lentils: A staple in many cuisines, important for dietary diversity.
Importance of Testing:
Legumes are prevalent in global cuisines and various food products, including:
- Vegan, vegetarian, and gluten-free foods
- Soups and salads
- Hummus and falafel
- Poppadoms, dahls, bhajis, dosas, and pakoras
- Curry powder mixes
- Chinese and Mexican dishes
- Healthy snacks (mixed nuts)
- Sports Supplements
- Worcestershire and BBQ sauces
Testing Methodology:
A blood sample is taken to assess the presence of IgE antibodies specific to legume proteins, providing a reliable indication of potential allergic reactions.
Interpretation of Results:
- Elevated IgE levels suggest a sensitivity or allergy to legumes.
- If necessary, results should be discussed with a healthcare provider for appropriate dietary management and further testing.
This test is crucial for individuals with suspected legume allergies. It enables informed dietary choices and effective management of allergic reactions.
Why would I need the Allergy Profile / Legume or Bean/Peas Test?
This test is recommended if you experience symptoms after consuming legumes, such as:
Skin reactions: Hives, eczema, itching, or swelling.
Gastrointestinal issues: Nausea, vomiting, diarrhea, or abdominal pain.
Respiratory symptoms: Wheezing, coughing, nasal congestion, or shortness of breath.
Anaphylaxis: Severe, potentially life-threatening reactions that involve difficulty breathing, swelling of the throat, or a drop in blood pressure.
Evaluation of suspected legume allergy: To determine if specific legumes (e.g., peanuts, soybeans, lentils, chickpeas) cause your symptoms and to help differentiate between cross-reactive allergens.
Family history: If you have a family history of legume allergies or a known allergy to one legume and need to check for cross-reactivity with other legumes.
What happens if my test results indicate a legume allergy?
If the test results show elevated levels of IgE antibodies to specific legumes:
Dietary modifications: To prevent accidental exposure, it's recommended to avoid all foods containing legumes and read food labels carefully.
Emergency action plan: If you are at risk for severe reactions, you might consider carrying an epinephrine auto-injector (EpiPen) in case of accidental exposure.
Further testing: Additional tests, such as an oral food challenge or skin prick test, may be conducted to confirm the allergy and assess its severity.
Consultation with an allergist: You may be referred to an allergist for specialized care and ongoing monitoring of your legume allergy.
