Understanding Lab Tests for Legume Allergy
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
A legume allergy is an immune system reaction to proteins found in legumes such as peanuts, soybeans, lentils, chickpeas, and green peas. While clinical diagnosis typically involves medical history and allergy testing, blood tests can provide valuable insights into immune responses to specific food allergens.
Recommended Test
IgG4 Food Panel IV
This comprehensive food panel can detect IgG4 antibodies to various foods including green peas and other legumes. Since green peas are part of the legume family, this test helps identify immune responses that may be associated with legume allergies, which can cause symptoms ranging from hives and stomach upset to severe anaphylaxis in sensitive individuals.

Blood tests don't directly diagnose food allergies, but they are fundamental for identifying immune system reactions to specific foods. These tests measure antibodies that your body produces in response to allergens, helping healthcare providers understand potential food sensitivities and guide dietary recommendations.
Understanding Legume Allergy Symptoms
Legume allergies can manifest in various ways, from mild digestive discomfort to severe allergic reactions. Common symptoms include hives, gastrointestinal upset, respiratory issues, and in severe cases, anaphylaxis. Blood testing helps identify which specific legumes may be triggering immune responses.
