To diagnose<unk>  after a referral is made for fast breathing (tachypnea) or need for extra oxygen. There are several tests that are commonly performed to confirm the diagnosis. Chest CT gives a better look at the lungs to see signs of pneumonia. With a bronchoscopy, a scope (small camera) is passed from the mouth or nose, through the windpipe, and into the lungs to check for other causes of breathing problems. A lung biopsy may be the only way to diagnose the disease if the chest CT does not show the characteristic findings. In a biopsy, a small portion of lung tissue is removed to determine if lung disease is present.
