The assessment of fat absorption forms an important part of the diagnostic process in some patients being investigated for possible malabsorption. This study has assessed the use of 13C-triolein as an alternative to the current 14C-triolein test for fat absorption. Initial work required an evaluation of performance characteristics of the isotope ratio mass spectrometer, observations on the normal variation in the exhaled breath 13CO2: 12CO2 ratio over one day, i.e. the effect of food and exercise, the investigation of a number of potential test meals to aid isotope delivery and the effect of 13C dose. A protocol has been developed for a test of fat absorption using 13C-triolein as the marker substrate and lemon mousse as the test meal. [Continues.]
