Take the diagnosis and management of soy-allergic patients to a whole new level

Why is soy allergy complicated to identify?


  • IgE-mediated allergy to soy might be the result of primary sensitization, but could also result from cross-reactivity to birch-related tree pollen and a variety of legumes.
  • IgE positivity to soy may be the result of different cross-reactivities, some without clinical reactions to soy.
  • For patients sensitized to birch pollen with a suspicion of soy allergy, it is recommended to extend the testing with Gly m 4, which can be underrepresented in available tests based on extracts.
  • Without components, it can be difficult to identify if your patient’s symptoms are actually due to soy.


Better identification of the soy-allergic patient...


  • The presence of specific IgE to the storage proteins Gly m 5 and Gly m 6 indicates real soy allergy and risk of severe reactions.
  • Sensitization to Gly m 4, a PR-10 protein, is common in patients allergic to birch-related tree pollen and indicates risk of reactions to soy. The reactions are often local, but might also be systemic.


...results in improved patient management


  • Evaluate your patient’s risk of severe reactions to soy.
  • Ensure relevant dietary advice and avoid unnecessary elimination.
  • Define the optimal treatment for your patients.
  • Proper diagnosis of patients with suspected soy allergy improves quality of life.
