Percent of predicted: We measure "normal" by measuring what you do relative to others of your age, gender, ethnicity, and body size. If you are 75% or more, it is considered normal.

See below: The DLCO should be between 80 and 120% of normal for you. The normals are calculated based on biographical data entered at the time of the test.
