DLCO (Diffusing Capacity) Interpretation and Predicted Value Calculator

Calculates predicted DLCO using GLI 2017 reference equations, interprets percent predicted severity categories, adjusts for hemoglobin, carboxyhemoglobin, and altitude, and guides ILD/pulmonary hypertension assessment.

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

Calculates predicted DLCO using GLI 2017 reference equations, interprets percent predicted severity categories, adjusts for hemoglobin, carboxyhemoglobin, and altitude, and guides ILD/pulmonary hypertension assessment

Each component has a specific meaning:

  • GLI 2017 reference equations — The gli 2017 reference equations recorded for the scenario being assessed.
  • Interprets percent predicted severity categories — The interprets percent predicted severity categories recorded for the scenario being assessed.
  • Adjusts — The adjusts recorded for the scenario being assessed.

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

How to Use

Enter the GLI 2017 reference equations, interprets percent predicted severity categories, adjusts for the scenario you are assessing. Calculates predicted DLCO using GLI 2017 reference equations, interprets percent predicted severity categories, adjusts for hemoglobin, carboxyhemoglobin, and altitude, and guides ILD/pulmonary hypertension assessment. Use the dlco calculator result to inform your calculation.
