A normal DLCO range for a healthy adult is typically above 75% to 80% of the predicted value based on your age, height, and gender. We use the 2017 ATS/ERS standards to ensure these measurements reflect your specific physiological needs accurately. If your results fall below 60% of the predicted value, it may indicate a moderate reduction in gas exchange efficiency. We prioritise these precise benchmarks to help you understand your respiratory health clearly.
