Abstract
A survey of the results of fecal fat determination in the gastrointestinal clinic from 1962 to 1966 was performed. At least a 72 hr. fecal collection is recommended for the determination. No definite diagnostic pattern, using fecal fat content and wet weight of stool, was established, but generally a heavy stool with high fat content suggested nontropicap sprue or pancreatic dysfunction, while a heavy stool with low fat content suggested regional enteritis. It was not possible to predict the fat content of the stool from the wet weight of the stool or vice versa, but only 1 stool that weighed less than 100 gin/day contained more than 5 gm/day.
