NCT03233256
Brief Summary:
This study proposes to demonstrate the feasibility of measuring 2H:1H and 18O:16O in saliva and breath by comparing the natural abundances of 2H:1H and 18O:16O in saliva and urine of un-dosed humans.
Detailed Description:
The scientific premises for this line of research are 1) challenges related to costs, the complexity of sample collection and preparation, and the level of technical skills required for Isotope-ratio mass spectrometry (IRMS) analysis have limited the adoption of the doubly labeled water (DLW) method; and 2) the investigators preliminary data demonstrates that Off-Axis Integrated Cavity Output Spectroscopy (OA-ICOS) provides a valid, more rapid, and less technically challenging approach to isotopic analysis of human samples.
