Tiny blood molecules may reveal lung damage in cystic fibrosis

This study investigates whether tiny molecules in the blood, called miRNAs, can act as markers of lung disease in people with cystic fibrosis. Researchers will compare miRNA patterns between cystic fibrosis patients and healthy volunteers, and also between patients with mild versus severe lung disease. The goal is to find a simple blood test that could help monitor lung health without invasive procedures.
