Pulmonary function tests: are they really necessary?
Abstract:
Pulmonary function tests and clinical evaluation can complement one another, but neither can take the place of the other. The tests can provide objective, reproducible assessment of a patient's pulmonary status. Pulmonary function tests can support clinical diagnoses, quantify the severity and variability of the disorder, and can assist early intervention by indicating problems likely to arise later in the course of the disease.

Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.
