GLI predicted values 2.0

GLI predicted values is a utility that helps clinicians, physiologists, and researchers calculate and interpret lung function using Global Lung Function Initiative (GLI) reference equations. By entering basic demographics and measured spirometry data, it provides predicted values, percent predicted, z-scores, and lower limits of normal (LLN) to support standardized, age-appropriate, and ethnicity-adjusted assessment of pulmonary function.

Key features:

• Uses GLI multi-ethnic reference equations across pediatric and adult age ranges
• Calculates predicted values, LLN, percent predicted, and z-scores for core spirometry indices (e.g., FEV1, FVC, FEV1/FVC)
• Accepts common input units with automatic handling of conversions
• Clear, structured outputs to aid reporting and clinical interpretation

Intended for:

• Respiratory and pulmonary clinics, lung function laboratories, and academic research settings
• Health professionals seeking consistent, guideline-aligned interpretation of spirometry

Note: This tool supports clinical decision-making but does not replace professional judgment or formal diagnosis. Users should verify settings and reference selections to match local protocols and patient populations.

GLI predicted values is developed by Philip H Quanjer. The most popular versions of this product among our users are: 2.0 and 3.0. The names of program executable files are GLI2012.exe, GLI2012_DataConversion.exe.
