Biomarkers and Pulmonary Function Test

A biomarker is an objectively measured characteristic that indicates normal or pathological state. Biomarkers of pulmonary function are clinical signs, radiological findings, or laboratory findings that reflect lung functions. In this chapter, we have classified biological markers of pulmonary functions in seven groups as clinical markers, lung volume and pressure markers, radiological markers, lung tissue, blood, sputum, and exhaled breath markers.
