[Advances of allergen component detection in the prevention and control of allergic diseases].

The incidence of allergic diseases in China is increasing year by year, which has caused heavy public health burden to individuals and society. The detection of specific IgE (sIgE) is an important way to diagnose the etiology of allergic disease. Currently, the diagnosis of allergic rhinitis In vitro mainly focus on the specific IgE of crude extracts in clinical practice, while the detection of sIgE in allergen components is rarely carried out. Clinicians, especially non-allergists, do not have sufficient understanding about the importance of sIgE in allergen component detection. Knowing the related types and clinical significance of allergen components can improve the diagnostic level of allergic diseases. Allergen component detection can distinguish the major components of common allergens, identify cross-sensitization, predict the risk of anaphylaxis, guide allergen immunotherapy and develop precise dietary regimens, so as to provide accurate prevention and control recommendations for patients.
