triolein breath test

triolein breath test

a breath test for pancreatic function. The fasting patient is administered triolein labeled with either carbon 13 or carbon 14, and levels of labeled carbon dioxide in the exhaled breath are subsequently measured at regular time intervals; low levels of carbon dioxide indicate inadequate pancreatic lipase, such as with a pancreatic disease or cystic fibrosis.

This patient had no evidence of fat malabsorption as measured by the triolein breath test.
The measurement of fecal fat excretion (1) remains an important test in the diagnosis of fat malabsorption despite the development of alternative biochemical investigations, such as the butterfat test (2), steatocrit (3), and triolein breath tests (4), and alternative diagnostic strategies in gastroenterology.
