Talk Abstract:

The success of breath-based biomarker discovery relies on a measurement technology that has been carefully engineered to measure a broad range of biologically relevant VOCs with high recision. The complex and poorly understood composition of the breath matrix makes this a significant challenge. This presentation introduces Owlstone Medical’s Breath VOC ATLAS; an ever-growing list of VOCs that exist on breath, differentiated from background contamination, and found repeatedly in a human population. We will discuss ways in which the VOC ATLAS paves the way for a breath VOC measurement platform with superior precision and reproducibility; attributes that are pivotal to biomarker discovery. The VOC ATLAS will enable the pooling of breath data and thus the ability to derive powerful biological insight to the breath matrix while also guiding study designs based on the known behaviour of VOCS in a population. We will present the methodology used to build the VOC ATLAS, including the study design, statistical methods and compound identification workflow based on Thermo’s Oritrap Q Exactive.
