[Bronchial challenge tests]

Area of Science:

• Pulmonology
• Allergology
• Occupational Medicine

Background:

• Bronchial challenge tests are essential for diagnosing respiratory conditions.
• A comprehensive diagnostic approach includes history, lung function, and allergy testing.

Purpose of the Study:

• To provide an updated overview of bronchial challenge tests.
• To detail their indications, contraindications, performance, and interpretation.
• To highlight their role in diagnosing respiratory sensitization.

Main Methods:

• Review of diagnostic schemes for respiratory sensitization.
• Inclusion of clinical history, occupational history, lung function testing, non-specific bronchial hyperresponsiveness assessment, and allergological diagnostics.
• Emphasis on specific bronchial challenge tests as the gold standard.

Main Results:

• Specific bronchial challenge tests are vital for confirming or excluding respiratory sensitization.
• These tests aid in therapeutic decisions, preventive measures, and insurance assessments.
• They require significant physician expertise.

Conclusions:

• Bronchial challenge tests are indispensable for diagnosing occupational respiratory diseases when other tests are equivocal.
• In most cases, a combination of history, lung function, and allergy tests suffices.
• Specific conjunctival or nasal challenge tests are recommended for upper respiratory or conjunctival allergies.
