Breath Test for Chemicals (Volatile Organic Compounds)
Completed
Conditions studied: Breath Tests, Human Volunteers, Pilot Study
In brief
Background: \- Some types of cancer, like cancer of the esophagus, are difficult to detect at an early stage. A possible detection method involves collecting breath samples to look for chemicals that may be signs of cancer. However, more research is needed to determine how different chemicals appear in different breath samples. This study will involve healthy volunteers. Objectives: \- To study chemicals appearing in breath samples of healthy volunteers. Eligibility: \- Healthy volunteers between 30 and 60 years of age. Design: * Participants will fast overnight (midnight to morning) and then provide two breath samples taken 5 minutes apart. * Breath samples will be collected on days 1, 49, and 98 of the study
