WebSep 22, 2024 · The FEV1/FVC is a ratio that reflects the amount of air you can forcefully exhale from your lungs. It's measured by spirometry, a test used to evaluate lung function. The FEV1/FVC ratio is often used in diagnosing and monitoring the treatment of lung diseases such as chronic obstructive pulmonary disease (COPD). WebThis is especially true if the DLCO score is 40% of predicted or lower. Accurate testing of DLCO at lower scores is more challenging. Research suggests that the percent predicted FVC is more sensitive for showing disease progression than the percent predicted DLCO. 5 For this reason, DLCO scores are not used at the primary endpoint in clinical ...
