Results may indicate malabsorption or maldigestion. False positive results can occur due to mineral oil or castor oil present in the specimen. Large number of neutral fat globules may indicate steatorrhea.
Patient should be on a normal diet which includes fat intake. Patient shouldnot use castor oil, mineral oil, suppositories or barium prior to collection of specimen.

Normal - Tiny fat globules, < 1 micron in diameter and too difficult to count, were observed microscopically under high power.
Abnormal - Fat globules, 1 to 8 microns in diameter, and < 100 globules per high power field were observed microscopically.
Grossly Abnormal - Large fat globules, 9 to 75 microns in diameter, and so numerous that there was very little fecal background observed microscopically under high power.
Limitations: Up to 12 grams of fat may be malabsorbed among patients with diarrhea even when the diarrhea is not attributable to fat malabsorption.
