Quick answer
The Legume Allergy Panel checks for IgE antibodies against several foods in the legume family in a single blood sample. Legumes include peanut, soybean, lentil, chickpea, pea, lupin, and others. Reactions can range from oral itching and hives to digestive symptoms and, in some cases, more serious responses. The panel helps show which legumes have caused sensitization when symptoms follow certain foods.
What this test measures
Legumes are seeds from plants in the Fabaceae family. They are common in many diets, and some, such as peanut and soybean, are among the more frequent food allergens. Because legumes share some proteins, a person may be sensitized to more than one.
The panel measures specific IgE antibodies to each legume included. A detectable level indicates sensitization to that food, but sensitization does not always cause symptoms. Results are interpreted with the reaction history and, in some cases, oral food challenge testing.
The panel may be ordered when someone has reacted to one legume and the provider wants to check for related sensitizations, or when the trigger food is unclear. A qualified healthcare provider should interpret the results and advise on which foods to avoid or evaluate further.
- Peanut-specific IgE antibodies
- Soybean-specific IgE antibodies
- Lentil-specific IgE antibodies
- Chickpea-specific IgE antibodies
- Pea-specific IgE antibodies
- Lupin-specific IgE antibodies
- Quantitative sIgE concentrations reported in kU/L
- Allergen-specific IgE class on a graded scale
Why people order this test
- Assess sensitization to multiple legumes with one sample
- Help evaluate reactions when the trigger food is unclear
- Check related legumes after a reaction to one
- Add objective information to a food allergy evaluation
- Compare sensitization patterns across legumes
- Support a clinician's dietary and management guidance
How to prepare
No fasting is required for this blood test. Follow the collection instructions provided by the laboratory, and have a record of which foods were eaten and when symptoms appeared.
Understanding your results
Results are usually available within one to three business days. Each legume is reported separately with a concentration and class. A qualified healthcare provider should interpret the panel with the reaction history, since sensitization does not always mean symptoms will occur.

Frequently Asked Questions
Which foods are tested in this panel?
Panels commonly include peanut, soybean, lentil, chickpea, pea, and lupin. The exact list depends on the panel ordered.
What if only one legume caused symptoms?
The panel can show whether related legumes have also caused sensitization. A healthcare provider uses that information to guide dietary advice.
Can I be sensitized without symptoms?
Yes. A positive IgE result shows sensitization, but some people do not develop symptoms when they eat that food.
Is peanut a legume?
Yes. Peanut is a legume, not a tree nut, which is why it is included in legume panels.
Does a positive result mean all legumes must be avoided?
Not necessarily. A healthcare provider can interpret the pattern and advise which foods need to be avoided or evaluated further.
