Improved diagnostic clarity in shrimp allergic non-dust-mite sensitized patients.

Background: Allergen specific immunoglobulin E (sIgE) levels predictive of shrimp allergy have not been identified, but these may be helpful in identifying patients at risk for shrimp-induced allergic reactions.

Objective: This study sought to identify component resolved diagnostic tests useful for diagnosis of shrimp allergy in patients with or without house-dust mite (HDM) sensitization to the major allergen cysteine protease (Der p 1).

Methods: Patients with positive skin-prick test (SPT) results and/or sIgE values were recruited.
