Upper airway test
An upper airway biopsy is obtained by using a flexible scope called a bronchoscope. The scope is passed down through the mouth and throat and a small piece of tissue is removed and sent to the laboratory. This test may be performed when an abnormality of the upper airway is suspected. It may also be performed as part of a bronchoscopy when abnormalities include the upper airway as well as the lung tissue.
