DLCO
The “diffusing capacity of the lungs for carbon monoxide,” also known as the transfer factor for carbon monoxide (TLCO), measures the amount of carbon monoxide (CO) transferred per minute from alveolar gas to red blood cells (RBCs). This test provides critical insights into the lungs’ ability to transfer oxygen from inhaled air to the bloodstream, making it essential for diagnosing and monitoring various pulmonary conditions.
