Answer

The typical bulky, greasy appearance and rancid odor of stools suggests malabsorption of fat. Findings from a Sudan stain of the stool might reveal fat droplets.

For a more quantitative measurement of fat absorption, a 72-hour fecal fat collection is frequently helpful in documenting steatorrhea.
