| Diagnosis | Clinical features | Testing |
| Allergic bronchopulmonary aspergillosis | History of asthma or cystic fibrosis Cough productive of phlegm with "bronchial casts" | Eosinophilia IgE: >1000 IU/mL Skin test: positive for aspergillus Aspergillus IgG: 2 fold elevation HRCT: mucous plugging, proximal bronchiectasis |
| Cardiac disease | Crackles or wheezes | B type natriuretic peptide: elevated Chest radiograph: increased interstitial opacities, ±cardiomegaly Echocardiogram |
| Chronic eosinophilic pneumonia | Asthma predates or develops in over 50 percent of patients Fever, weight loss, and night sweats are common | Peripheral blood: ±eosinophilia Chest radiograph: bilateral peripheral opacities BAL: eosinophilia >40 pecent |

| COPD | Smoking history | PFTs: irreversible airflow obstruction and sometimes low DLCO |
| GERD | May complain of chest tightness/restriction or nocturnal choking | Response to empiric treatment with PPI pH probe monitoring: acid reflux Spirometry normal, methacholine negative* |

| Tobacco smoke exposure | History | |
| Inducible laryngeal obstruction (vocal cord dysfunction) | Hoarseness/stridor (can be inspiratory and/or expiratory) Symptoms provoked by exercise | Flow volume loop: slowing on inspiration Direct laryngoscopy (possibly during exercise or methacholine challenge): abnormal cord motion |
