Tests and diagnosis

By Mayo Clinic Staff

Your doctor will ask about your symptoms and may perform a physical exam. He or she may recommend one or both of the following tests:

  • Skin test. Your skin is pricked and exposed to small amounts of the proteins found in soy. If you're allergic, you develop a raised bump (hive) at the test site on your skin. Allergy specialists usually are best equipped to perform and interpret allergy skin tests.
  • Blood test. A blood test can measure your immune system's response to soy by measuring the amount of certain antibodies in your bloodstream, known as immunoglobulin E (IgE) antibodies.
