Pulmonary function tests confirm diagnosis of restrictive lung disease

Pulmonary function tests (PFTs) show results consistent with a reduced ability of the lungs to expand fully, indicative of restrictive lung disease.

Used when PFT results support a pre-existing suspicion or establish a new diagnosis of restrictive lung disease.

This phrase should be used only when PFT results definitively support the diagnosis. It should not be used if the PFT results are inconclusive or suggest an alternative diagnosis.
