Quick answer
The Lentil Allergy Test detects IgE antibodies against proteins in lentils. Lentils are a legume commonly used in soups, stews, curries, and salads. Reactions can range from itching or tingling in the mouth to hives, digestive symptoms, and in some cases more serious responses. Because lentils are related to other legumes, testing can help show whether sensitization extends to foods such as chickpea or pea.
What this test measures
Lentils are edible seeds from the legume family, related to chickpea, pea, peanut, and soybean. They are rich in protein and fiber and feature in many traditional cuisines. Allergy to lentil is reported in some regions more than others, often alongside allergy to other legumes.
The test measures specific IgE antibodies to lentil in a blood sample. A detectable level indicates sensitization, which may or may not cause symptoms. Because legumes share proteins, results are often interpreted with tests for related foods and with the reaction history.
Testing may be considered when someone reports symptoms after eating lentils or mixed legume dishes. Cooked and raw forms can behave differently, and some reactions occur mainly with raw flour or dust. A qualified healthcare provider should interpret the result and advise on management.
- Lentil-specific IgE antibodies
- Quantitative sIgE concentration reported in kU/L
- Allergen-specific IgE class on a graded scale
- Total serum IgE when included
- Blood eosinophil count when included
- Related legume markers when a panel is included
Why people order this test
- Assess sensitization after reactions to lentils
- Help evaluate oral, skin, or digestive symptoms with exposure
- Check for related legume sensitizations
- Add objective information to a food allergy evaluation
- Support a clinician's dietary guidance
- Provide context when lentil flour or dust triggers symptoms
How to prepare
No fasting is required for this blood test. Follow the collection instructions provided by the laboratory, and note whether symptoms followed cooked lentils, raw flour, or another form.
Understanding your results
Results are usually available within one to three business days. A detectable level indicates sensitization to lentil proteins, but not everyone who is sensitized develops symptoms. A qualified healthcare provider should interpret the findings with the reaction history.

Frequently Asked Questions
Is lentil allergy common?
Lentil allergy is reported in some regions more than others and often appears alongside allergy to other legumes. It can affect children and adults.
Can lentil allergy be related to other legumes?
Yes. Legumes share some proteins, so people with lentil allergy may also be sensitized to chickpea, pea, peanut, or soybean.
Does cooking lentils change the allergen?
Cooking can change some proteins, and reactions may differ between cooked lentils and raw flour or dust. A healthcare provider can assess the specific pattern.
What symptoms suggest lentil allergy?
Oral itching or tingling, hives, swelling, stomach upset, and breathing difficulty are possible symptoms. Severe reactions require urgent medical care.
Does a positive test mean I must avoid all legumes?
Not necessarily. A healthcare provider can interpret the result and advise which foods should be avoided or evaluated further.
