The aim of this study is to evaluate serum specific-IgE in a large group of polysensitized patients with the same SPT result (such as ++++) comparing two diagnostic methods. Six hundred ten patients (310 females; median age 32 years) suffering from allergic rhinitis were studied. Serum specific-IgE were measured by ImmunoCap assay. Skin prick test was also performed. There was a significant difference between serum specific-IgE values in these polysensitized patients. In conclusion, the serum specific-IgE measurement in polysensitized patients seems to be more appropriate than SPT.
