This study aims to reduce the cost of allergen testing for Guangzhou, China by limiting the number of allergens for which patients are tested, and provide a testing panel to improve diagnostic and therapeutic efficiency. This retrospective study of real-world data from 2012 to 2019 included 39,570 patients with suspected allergies in Guangzhou, southern China. All the patients were tested for one or more of the following allergens serum specific immunoglobulin E (sIgE): Dermatophagoides pteronyssinus , Dermatophagoides farinae , cat dander, dog dander, Artemisia vulgaris , Aspergillus fumigatus , Alternaria alternata , Blattella germanica , egg whites, milk, wheat, peanuts, soybeans, Cancer pagurus , and Penaeus monodon by PhadiaCAP 1000. Totally, only the positive rates of allergens sIgE in D. farinae , D. pteronyssinus , milk, egg whites, B. germanica , C. pagurus , A. alternata , and P. monodon were > 10%, the other allergens were between 4–7%. Moreover, among the allergic diseases, dust mites exhibited the overall highest positive rate, followed by milk and B. germanica . In children, milk was the main allergen, whereas in adults, mites, cockroaches, shrimp, and crab allergens had higher positive rates. The optimal scale analysis shows that the multiple sensitization classification of patients can be divided into three categories: I D. farinae and D. pteronyssinus ; II. C. pagurus , P. monodon , and B. germanica ; III. Milk and egg whites. Generally, a panel including 4 allergens can detect > 90% of the potential allergy in this local population. In Guangzhou, southern China, D. farinae , milk, B. germanica , and A. alternata as a panel screening allergy for suspected allergic patients was suggested base on this study.
