Buckwheat is an annual plant of the Polygonaceae family, containing proteins, fats, carbohydrates, flavonoids, and tannins. Buckwheat pollen grains have two types: large and small. Buckwheat allergens are thermostable, retaining their activity even after heat treatment.
Buckwheat allergy is common in many countries worldwide, especially in Asia. It can manifest as urticaria, asthma, atopic dermatitis, allergic rhinitis, and in severe cases – anaphylaxis. The main route of allergic exposure is buckwheat consumption, as well as inhalation of buckwheat hull pollen, for example, from pillows.
Buckwheat has cross-reactivity with rice, nuts, latex, and other products. Detection of specific IgE to buckwheat helps establish an accurate diagnosis, avoid the allergen, and manage treatment.
FEIA (Fluorescence Enzyme Immunoassay), ImmunoCAP (Solid-phase Immunofluorescence) – quantitative determination of specific IgE to buckwheat allergen.
