Although medicine has long sought methods to study fecal fat without studying feces, the 72-hour stool collection for quantitative determination of fecal fat (1) remains the gold standard for identifying patients with steatorrhea. In practice, this test is often inadequately done because of difficulties in controlling fat intake and in ensuring adequate sample collection. The esthetic problems of sample collection and analysis mean that results are seldom returned promptly to the clinician, limiting the test's utility as a screening procedure for steatorrhea. The prompt, semiquantitative information available from microscopic examination of stools stained for fat with Sudan III is underutilized
