Use of the Biphasic ¹³C-Sucrose/Glucose Breath Test to Assess Sucrose Maldigestion in Adults with Functional Bowel Disorders

Figure 2

To validate breath sample enrichment outcomes, the relationship between ¹³CO₂-breath sample oxidation data and ¹³CO₂-plasma fermentation data was determined for the four genetically SI-characterized subjects (chromosome 3-NC_000003.12). Subjects undertook ¹³C-S/GBT with simultaneous blood sampling for plasma glucose fermentation to release ¹³CO₂. Phase I ¹³C-sucrose oxidation data and plasma fermentation data are shown.
