We are excited to be co-presenting two research posters at next year’s Digestive Disease Week conference in Chicago.

The first is titled: Establishing Normal Values for Gastrointestinal Hydrogen Sulphide Production in Breath Using Selected-Ion Flow-Tube Mass Spectrometry (SIFT-MS) and explores how current techniques that can measure Hydrogen Sulfide may not be sensitive to detect pathological changes due to their sensitivity. In this study we used a technique called SIFT-MS to detect parts per billion range of Hydrogen Sulfide and outlined how the stability of Hydrogen Sulfide in PVDF bags means it could be a viable technique for at home and in clinic testing. However, further studies in patients with IBS and IBD are needed to establish pathological range of Hydrogen Sulfide production.

Our second poster is: Novel Real-Time Assessment of Endogenous and Exogenous Volatile Organic Compounds on Breath in Healthy Subjects – Next Generation Biomarker Development for Digestive Health. This work looked at how the microbial fermentation of carbohydrates produces metabolic by-products including short chain fatty acids that can be measured on breath.
