Clinical Experiences in 14C-tripalmitin breath test for fat malabsorption.

The 14C-tripalmitin breath test has been used routinely in our institution for the diagnosis of fat malabsorption as well as for the differential diagnosis of malabsorption due to pancreatic insufficiency. The test was performed in 124 patients over a period of about three years. The sensitivity and specificity of the test for fat malabsorption were better than 85.7 and 87.0%, respectively, with the efficiency better than 86.4%. When used in conjunction with Viokase administration, the test is useful as a means of separating pancreatic malabsorption patients from patients with other forms of malabsorption.
