Summary
The intranasal allergen provocation test (INT) shows high reproducibility for diagnosing grass allergies extraseasonally. Standardized conditions ensure reliable results for allergic rhinitis management.
Area of Science:
- Allergy and Immunology
- Otolaryngology
- Respiratory Medicine
Context:
- Perennial allergic diseases of the upper respiratory tract are increasing.
- Accurate allergen identification is crucial for effective treatment.
- The intranasal allergen provocation test (INT) is a key diagnostic tool.
Purpose:
- To assess the extraseasonal reproducibility of the INT.
- To standardize INT methodology for allergic rhinitis diagnosis.
- To evaluate the reliability of INT in patients allergic to graminaceae.
Summary:
- The study investigated the reproducibility of the INT in 21 patients with graminaceae allergy.
- Standardized conditions included lyophilized allergen, inferior concha application, and rhinomanometry.
- A 30% nasal airflow reduction was the borderline for a positive test, showing high reproducibility.
Impact:
- The findings support the INT as a reliable method for diagnosing specific allergen sensitization.
- Standardized INT protocols can improve diagnostic accuracy for allergic upper airway diseases.
- Addressing allergen concentration is key to optimizing INT clinical utility.
