Sunflower is a widely cultivated crop globally, and products from its seeds are used for oil production and animal feed. Allergy to sunflower seeds is rare but can cause severe reactions, including anaphylaxis. The main allergens are lipid transfer protein (Hel a3) and 2S protein (Hel a2S). Cross-reactions with pollen, tree nuts, and other seeds have been identified.

Occupational sensitization to sunflower seeds is associated with the development of asthma and allergic rhinitis symptoms in workers exposed to sunflower. Symptoms disappear upon allergen avoidance. Smoking and atopy increase the risk. Anaphylactic reactions have been reported in patients after consuming seeds or products prepared with sunflower oil.

  • Diagnosis of allergic reactions to sunflower seeds.
  • Assessment of sensitization level and risk of allergy development.
  • Monitoring therapy effectiveness.
  • Evaluation of sensitization level after allergen avoidance.
  • Assessment of immune system status.

FEIA (Fluorescence Enzyme Immunoassay, ImmunoCAP (Solid-phase Immunofluorescence)) – quantitative determination of the allergen.
