A pilot study on the allergen-specific IgE to molecular components on polysensitized mite allergic asthmatic patients in Guangzhou, China.

•The sensitization of 112 allergen components among mite allergic polysensitized asthmatic patients from southern China.•Sensitization to rDer p 10 was correlated to food allergy in mite allergic polysensitized asthmatic patients.•Positive rate to nPhl p 4 was significantly higher in the patients with AA + AR than those with AA only.•Singleplex ImmunoCAP usually detect more positive cases than ISAC.
