Steatorrhea, a simple and rapid method of diagnosis.

A simple and rapid method for the diagnosis of steatorrhea is described. 
The method is based on the assessment of the difference of 
specific gravity and lipophilic property between a normal stool and that 
in steatorrhea, using a benzene-NaBr system. The stool samples are dried, 
pulverized, and then investigated. Steatorrhea is defined either as a fat 
or more in a 24-hour sample. Stool samples of 71 infants 
and children were examined. Among these were 23 healthy subjects, 10 
with upper respiratory tract infections, and 6 with pneumonia. A further 
31 children had celiac disease, 9 of them were on a 
gluten-free diet, and one child had cystic fibrosis. The procedure described 
renders single stool samples suitable for the assessment of steatorrhea. As 
a screening test the method proved to be rapid and accurate 
in the diagnosis of steatorrhea.
