title: A non-invasive test of gastric function.
abstract: Using 98Tcm a non-invasive test of gastric function has been developed which completely obviates the need for a nasogastric tube and which adds to the accuracy of existing tests by overcoming losses due to incomplete aspiration or gastric emptying. 99Tcm is handled by the stomach like Cl-, the gastric secretion of which is equal to that of H+. The value of the pentagastrin stimulation test in the presence of varied gastric pathology is discussed in relation to 50 patients. Other possible diagnostic uses of the test are evaluated and a method of carrying out an insulin test by a modification of the technique is described.
