A method for measuring the absorption of I131-labeled fat is presented.

In normal infants the degree of fat absorption, by the method presented, appears to be a function of age.

In infants and children with cystic fibrosis of the pancreas the test provides a means of studying the lipolytic function of the pancreas and the efficacy of the addition of pancreatic extracts to the diet.

The test provides a means of recognizing the presence and severity of the celiac state where it is a factor in malnutrition.
