Concordance of skin prick test and serum specific-IgE to locally produced-component-resolved diagnostics for cockroach allergy

Cockroaches (CR) are ubiquitous insects of public health concern as they are not only a potential source of pathogens, but also produce potent allergens that are hazardous to human health. It has been estimated that there are 4,000 extant species of CR. Whereas most species dwell in tropical and subtropical forests, about 50 species have adapted to life as domiciliary pests within the human environment.1 In Thailand, the American cockroach Periplaneta americana is predominant species.2 Exposure to cockroach (CR) allergens represents a high risk for IgE sensitization3,4 and allergic symptoms, particularly allergic rhinitis and atopic asthma after allergen reexposure.
