DLCO %Predicted Correction for Haemoglobin

Correct the measured DLCO (diffusing capacity of the lung for carbon monoxide) for haemoglobin concentration to avoid misinterpreting anemia-related reductions as true diffusion impairment.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Correct the measured DLCO (diffusing capacity of the lung for carbon monoxide) for haemoglobin concentration to avoid misinterpreting anemia-related reductions as true diffusion impairment

Each component has a specific meaning:

  • Capacity of the lung — The capacity of the lung recorded for the scenario being assessed.

Note: Interpret the dlco hb correction result against the thresholds and context described above.

How to Use

Enter the capacity of the lung for the scenario you are assessing. Correct the measured DLCO (diffusing capacity of the lung for carbon monoxide) for haemoglobin concentration to avoid misinterpreting anemia-related reductions as true diffusion impairment. Use the dlco hb correction result to inform your calculation.
