Prospective Analysis of Urine LAM to Eliminate NTM Sputum Screening

Description

This is a prospective, single-center, nonrandomized observational study to investigate the utility of urine lipoarabinomannan (LAM) as a test to identify individuals at very low risk for having a sputum culture positive for Nontuberculous Mycobacteria (NTM). The study is designed to evaluate if a urine test can eliminate the need for obtaining a sputum specimen to screen for NTM in individuals with Cystic Fibrosis (CF). The participants will be asked to provide 3 urine samples either in person or by mail over approximately 3 years. The 3 urine sample requests will be timed to coincide with their usual clinical care and routine sputum collection.
