Question: How doctors diagnose lung disease
Answer: Depending on your symptoms and health history, your provider might use some of these tests to diagnose lung disease:
1. Pulmonary function tests: Providers can use spirometry and other tests to see how well your lungs are working.
2. Pulse oximetry: This test uses a device on your finger to measure oxygen levels in your blood.
3. Imaging tests: Chest X-rays and CT scans can look for lung changes and damage.
4. Blood tests: Blood tests can check your overall health. Your provider might also order special types of blood tests, like an arterial blood gas test or genetic testing.
5. Bronchoscopy: Your provider can use this procedure to look inside your airways and take tissue and fluid samples for biopsy.
6. Electrocardiogram (ECG or EKG): This test checks heart function and rules out heart disease as the cause of your symptoms.
7. Exercise testing: Your provider uses this to determine if the oxygen level in your blood drops when you exercise.
8. Biopsy: Your provider might test a small amount of tissue to diagnose certain lung diseases, like cancer or pulmonary fibrosis.
