Accuracy Of Skin Prick Test Using In-house Wheat Extract For The Diagnosis Of IgE-mediated Wheat Allergy: A Pilot Study
Accuracy Of Skin Prick Test Using In-house Wheat Extract For The Diagnosis Of IgE-mediated Wheat Allergy: A Pilot Study
Nowadays, commercial wheat extract is widely accessible, and is used for skin prick test for wheat allergy. However, commercial wheat extracted for skin prick test have less precise test result compared to extract from omega-5 gliadin, which is one of the major allergen with immediate wheat allergy.

Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Wheat Allergy
Other: Commercial extract and in-house wheat extract
Patients with a history of wheat allergy underwent two skin test extracts, and open challenge with wheat. A blood test for specific IgE was performed in the same time.
Experimental: Food challenge, skin test
Skin test by two extract commercial, and in-house extract. and open challenge with wheat (except in patient with history of wheat anaphylaxis: assume as challenge positive)
