sputum culture and sensitivity
Testing sputum by placing it on a culture medium and observing any bacterial growth. The specimen is then tested to determine antibiotic effectiveness.
sputum cytology
Examining sputum for malignant cells.
bronchogram
X-ray record of the bronchus produced by bronchography.

oximetry
Measures the oxygen level in the blood using a device, an oximeter, placed on the patient’s fingertip or earlobe.
pulmonary function test (PFT)
Group of diagnostic tests that give information regarding air flow in and out of the lungs, lung volumes, and gas exchange between the lungs and bloodstream.
spirometer
Instrument to measure lung capacity used for spirometry.
spirometry
Procedure to measure lung capacity using a spirometer.
polysomnography
Monitoring a patient while sleeping to identify sleep apnea. Also called sleep apnea study.
sweat test
Test for cystic fibrosis. Patients with this disease have an abnormally large amount of salt in their sweat
