To assess the diagnostic performance of Der p 1 and Der p 2 specific IgE (sIgE). Studies were systematic computerized searches of the PubMed, EMBASE, and Cochrane libraries (published 1966 to September 5, 2015). Records were screened by title and abstract and then by full-text articles of relevant studies. Eligible studies were selected according to inclusion criteria: (1) all house dust mite allergy diagnosed on the basis of clinical symptoms in combination with a dust mite extract skin prick test result; (2) the inclusion of controls in the study; and (3) enough data to construct the diagnostic 2 × 2 table. True-positive, false-positive, false-negative, and true-negative values were extracted from or calculated for each study. Then the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were calculated. A summary receiver operating characteristic curve and area under the curve were used to evaluate the overall diagnostic performance. Seven eligible studies that involved 1040 cases were included in this meta-analysis. The meta-analysis found that detection of Der p 1 or Der p 2 sIgE is of sufficient diagnostic accuracy for use in the diagnosis of Dermatophagoides pteronyssinus IgE sensitization. Detection of Der p 1 or Der p 2 sIgE is a promising diagnostic tool in the diagnosis of D pteronyssinus IgE sensitization. Copyright © 2016 American College of Allergy, Asthma & Immunology.
