- CXR showing interstitial pattern
- PFTs showing low DLCO and FVC (i.e. a restrictive pattern
- High-res CT scan showing a UIP pattern
- Subpleural/basal
- reticulation
- Honeycombing
- No incosistent features
- If high-res CT indeterminate, consider biopsy (but 5% mortality from biopsy in ILD)
- CBC, electrolytes
- ANA/ENA, RF, CCP
- Precipitating antibodies
Management
- Smoking cessation
