PG - 385-388 LID - 10.1002/alr.21890 [doi] AB - BACKGROUND: The purpose of this study was to determine if total serum immunoglobulin E (IgE) could predict monosensitization compared to polysensitization in patients with allergic rhinitis (AR). METHODS: This was a retrospective study of a cohort of 1073 patients who underwent allergy testing. Differences in total IgE level between unsensitized, monosensitized, and polysensitized subjects were calculated. Pearson correlation coefficient was calculated to determine whether there was a relationship between total IgE level and the number of positive allergen sensitizations. In addition, allergen sensitization class was calculated for each allergen sensitization and totaled for each patient. Pearson correlation coefficient was calculated to determine the relationship between total IgE level and weighted allergen sensitization by class. RESULTS: There were 159 patients who were monosensitized compared to 492 patients who were polysensitized. Of the monosensitized patients, almost 50% (74) were sensitized to one or both dust mites. Total IgE was higher in polysensitized patients compared to monosensitized compared to controls (p < 0.001). Pearson correlation coefficient between total IgE and number of positive allergen sensitizations was 0.465 (p
