ALEX2 multiplex examination – results of specific IgE to fish and shrimps in patients suffering from atopic dermatitis

Abstract

The sensitivity of ALEX2 Allergy Explorer test in patients suffering from atopic dermatitis and clinical reactions to fish/shrimps was evaluated. We compared the results of specific IgE to allergen reagents (molecular components) and clinical reactions in the open exposure test (patient’s history); the sensitivity was calculated with Fisher's Exact test (Rates and Confidence Intervals 95% C. I., value, lower, upper). Altogether 100 atopic dermatitis patients were examined. We confirmed significant relationship between the results of specific IgE to allergen reagents (molecular components) of fish and the results open exposure test/history; the sensitivity is in the range of 33.3% (7.49%–70.07%)–44.4% (13.7%–78.80%). We did not confirm the significant relationship between the results of specific IgE to allergen reagents (molecular components) of shrimps and the results open exposure test/history; the sensitivity is in the range of 0%–40% (5.27%–85.34%).
