A standardised nutritional drink as a test meal for the C mixed triglyceride breath test for pancreatic exocrine insufficiency: A randomised, two-arm crossover comparative study.

Abstract

The 13 C mixed triglyceride breath test (13 C MTGT) is a diagnostic test for pancreatic exocrine insufficiency (PEI). It is poorly standardised with much heterogeneity of the test meal, the commonest being toast and butter. A standardised oral nutritional supplement that could be easily transported, stored and made up would be valuable for making this test accessible outside of specialist centres.
