BACKGROUND Skin prick test (SPT) and serum specific IgE (ssIgE) measurements are the most common methods used to diagnose allergy. The aim of this study was to evaluate serum specific-IgE in a large group of polysensitized patients with the same SPT result (such as ++++) comparing the two diagnostic methods. METHODS Four hundred ninety-four children (310 males; median age 10 years) suffering from allergic rhinitis were studied. Serum specific-IgE values were measured by ImmunoCap assay. Skin prick test was also performed. RESULTS There was a significant difference (p < 0.0001) among serum specific-IgE values in these polysensitized patients. CONCLUSIONS The ss-IgE measurements in polysensitized patients seem to be more appropriate than SPT.

UI MeSH Term Description Entries
D007073 Immunoglobulin E An immunoglobulin associated with MAST CELLS. Overexpression has been associated with allergic hypersensitivity (HYPERSENSITIVITY, IMMEDIATE). IgE
D007114 Immunization Deliberate stimulation of the host's immune response. ACTIVE IMMUNIZATION involves administration of ANTIGENS or IMMUNOLOGIC ADJUVANTS. PASSIVE IMMUNIZATION involves administration of IMMUNE SERA or LYMPHOCYTES or their extracts (e.g., transfer factor, immune RNA) or transplantation of immunocompetent cell producing tissue (thymus or bone marrow).

D012221 Rhinitis, Allergic, Perennial Inflammation of the mucous membrane of the nose similar to that found in hay fever except that symptoms persist throughout the year. The causes are usually air-borne allergens, particularly dusts, feathers, molds, animal fur, etc. Rhinitis, Allergic, Nonseasonal
D012680 Sensitivity and Specificity Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed) Specificity,Sensitivity,Specificity and Sensitivity
D012882 Skin Tests Epicutaneous or intradermal application of a sensitizer for demonstration of either delayed or immediate hypersensitivity. Used in diagnosis of hypersensitivity or as a test for cellular immunity. Skin Test,Test, Skin,Tests, Skin
