Abstract
Breath sampling and analysis provide healthcare professionals with a practical, noninvasive diagnostic measurement for children with a variety of gastrointestinal (GI) disorders. New biomarkers found in human breath have been investigated and provide the opportunity to diagnose bacterial overgrowth and other underlying causes of GI dysfunction. Although several protocols have been described previously regarding breath sampling, few have demonstrated the feasibility of collection in young children. This communication introduces a simple game that allows for 3- to 7-year-old children to practice breath exhalation to give a proper breath sample in a relaxed and comfortable environment. The technique described offers clinicians a creative approach for obtaining breath samples from a child by reducing the apprehension and anxiety associated with the research and clinical environment.
