title: Tests of intestinal function.
abstract: The most important tests for investigating the functions of the small bowel are faecal-fat analysis, the determination of xylose tolerance, vitamin-B12 absorption, and 14C-glycoholate transport, barium examination of the small bowel, and small bowel biopsy. With these tests, most disorders of digestion and of absorption can be adequately investigated and diagnosed.
