We collected 3 mL of venous blood to separate the serum for use and used the Fubok allergen detector and its allergen diagnostic reagent produced by Jiangsu Haooubo Biological Medicine Co., Ltd. (Suzhou, Jiangsu Province, China) to determine the specific IgE of the corresponding allergen in the serum. The system adopts the enzyme-linked immunostaining method to detect the serum-specific IgE content, which is a quantitative detection. Inhalation allergens include house dust mites, dust mites, mugwort, ragweed, cockroaches, cat epithelia, dog epithelia, house dust, Alternaria, and willow. Food allergens include peanut, egg, milk, cod, wheat flour, shrimp, soybean, crab, beef, and mutton.
