Diagnosis of Hypersensitivity Pneumonitis in Adults
Key Points
Key Points
- Hypersensitivity pneumonitis (HP) must be considered in the differential diagnosis for patients with newly identified interstitial lung disease (ILD).
- This guideline committee categorized HP into two clinical phenotypes—nonfibrotic and fibrotic HP—and made separate recommendations for each.
- makes no recommendation or suggestion for or against the use of a questionnaire to identify potential HP inciting agents and sources. Instead, the guideline committee recommends development and validation of a questionnaire.Remark: Pending the availability of a validated questionnaire, the guideline committee advocates that clinicians take a thorough history to identify potential exposures and sources in the patient's environment that are known to be associated with HP.
