Summary
This study proposes a harmonized international standard series for patch testing, reducing the current 32 allergens to a minimal set of 20 and an extended set of 14 for broader allergen coverage.
Area of Science:
- Dermatology
- Allergology
- Immunology
Background:
- Current standard patch test series vary regionally (European, North American, Japanese).
- These series present 32 allergens, reflecting regional differences in allergen prevalence and dermatological consensus.
- Discrepancies in standard allergen series can impact diagnostic accuracy and research comparability.
Purpose of the Study:
- To propose a unified "minimal" international standard series of 20 allergens.
- To propose an "extended" international standard series of 14 allergens.
- To harmonize global patch testing practices and allergen standardization.
Main Methods:
- Comparative analysis of existing major standard patch test series.
- Identification of core allergens based on prevalence and clinical relevance.
- Development of proposed "minimal" and "extended" international standard series.
Main Results:
- A proposed "minimal" international standard series comprising 20 allergens.
- A proposed "extended" international standard series comprising an additional 14 allergens.
- The proposed series aim to balance comprehensiveness with practicality.
Conclusions:
- A harmonized international standard series for patch testing is feasible.
- The proposed series can improve global consistency in diagnosing allergic contact dermatitis.
- Standardization will enhance comparability of research and clinical outcomes worldwide.
