Diagnosing pulmonary fibrosis (PF) is complicated because symptoms may mirror those of other lung disorders such as asthma, pulmonary hypertension or chronic obstruction pulmonary disease (COPD). Because of this, six different diagnostic tools are needed for an accurate diagnosis of PF, according to the American Lung Association.

1. Chest X-ray

Chest x-rays take a picture of the structure of the heart and lungs, which allows doctors to look for any shadows that may point to the presence of scar tissue.

2. Lung Function Tests

Patients are required to take a deep breath and then blow into a machine which measures the amount of air exhaled and the speed in which it’s exhaled. This helps doctors picture the level of lung damage.

3. Blood Tests

Patients are asked to provide blood samples to check the levels of oxygen in the bloodstream and to see if there are any infections present. The levels of carbon dioxide and oxygen in a patient’s bloodstream can also be measured using an arterial blood gas test.

4. Lung Biopsy

A lung biopsy is the removal of a small sample of tissue which can be studied to assess damage. This can be done either as a surgical procedure or during a bronchoscopy.

5. CT Scan 

In addition to a chest x-ray, doctors may request a high-resolution computed tomography (HRCT) scan which will show the lungs in better details. This gives doctors more precision than regular x-rays.

6. Exercise Testing

Another way to discover how well the lungs are functioning is an exercise test. Patients will be required to either walk or pedal on a stationary bike for a few minutes, which allows the doctor to see how well the lungs are delivering oxygen and removing carbon dioxide.
