9258. Allergen. Extract. Rape (pollen, w203), IgE antibodies
Description
Oilseed rape (Brassica napus) is an annual oil crop of the Brassicaceae family, whose pollen is a widespread inhalant allergen carried by wind over considerable distances. The flowering season falls in May-June. Clinical manifestations include rhinoconjunctivitis, sneezing, pruritus, and urticaria; in more severe cases – bronchial asthma and angioedema. Due to the presence of profilins, cross-reactivity with other Brassicaceae plants, fruits, and vegetables is possible. Determination of specific IgE antibodies to rapeseed pollen confirms sensitization and helps assess the risk of clinical manifestations.
When and who needs the test?
The test is recommended for both adults and children to determine the cause of allergy in the presence of symptoms such as rhinoconjunctivitis, sneezing, itching, urticaria, bronchial asthma, or angioedema.
Indications for testing:
- seasonal pollinosis (hay fever);
- allergic reactions after consuming fruits and vegetables (apple, carrot, tomato, melon);
- unexplained respiratory or skin symptoms during the spring–summer period;
- atopic dermatitis;
- food allergy when cross-sensitization is suspected.
