Estimating Risk of Respiratory Infections Attributable to CFTR Heterozygosity
Sponsor: Philip Polgreen
Summary
A research team member will brush the inferior surface of the subjects' middle turbinate (nasal cavity) using a cytology brush to obtain the cells needed to perform our functional respiratory assays. An individual trained in phlebotomy will draw one 3 ml lavender top tube of blood to test c-reactive protein, calprotectin, and lactoferrin. They will also draw a 5 ml gold top serum separator tube of blood to test fibroblast growth factor-19. The participant will answer questions from the baseline survey and report their current medications interview-style with the research team member.
