QuinTron has partnered with EndoNurse Magazine to publish an educational eBook on Breath-Testing for nurses and technicians to help continue their knowledge of breath testing and QuinTron's products. Breath tests are invaluable in helping evaluate functional bloating, diarrhea, constipation and suspected malabsorption. These tests are simple and safe alternatives compared to more invasive procedures such as biopsies and/or obtaining aspirates for culturing. Hydrogen breath tests aids in the diagnosis of Small Intestinal Bacterial Overgrowth (SIBO) which provides a framework for understanding Irritable Bowel Syndrome (IBS) patients. The types of gas produced by bacteria in the digestive tract are an important factor in this understanding. Recent work demonstrates that among IBS subjects, methane produced during lactulose breath testing is associated with constipation predominance both subjectively and objectively.
