Relative Value of Tests for Intestinal Malabsorption
Abstract
In the investigation of 79 patients to establish the presence or absence of intestinal malabsorption, the most accurate pointers to malabsorption were established. A good test should be abnormal in most patients with malabsorption, and be normal in normal patients. The investigations adhering nearest to these criteria were found to be jejunal biopsy, barium meal and follow-through, and Schilling and xylose tests. Stool fat estimat:on, glucose tolerance and vitamin A tolerance were less useful tests of malabsorption. There was no correlation between stool fat excretion and vitamin A tolerance.
