Evaluation of a Particle Enhanced Turbidimetric Immunoassay (PETIA) for detecting calprotectin in sputum samples
BackgroundChronic obstructive pulmonary disease (COPD) and cystic fibrosis (CF) are characterized by persistent airway inflammation and airflow limitation. Measuring airway inflammation may be of value both in research and clinical practice. Calprotectin, a protein associated with neutrophil activation, serves as a potential biomarker for airway inflammation. This study evaluates the performance o
