Detailed explanation-1: -Screening for steatorrhea may be carried out by examining stool samples for the presence of fat by Sudan III staining. However, quantitative fecal fat estimation is required to confirm the diagnosis.
Detailed explanation-2: -Steatorrhea occurs when stimulated lipase output drops to less than 5% to 10% of normal. Thus, measurement of fat in the stools collected for 72 hours in a subject ingesting a diet adequate in fat intake (70 to 100 g/day) is considered an effective means of diagnosing steatorrhea.
Detailed explanation-3: -Fat in stool may be detected with the qualitative fecal fat test, which generally determines the presence or absence of excess fat. This test is performed by placing a suspension of treated or untreated stool onto a glass slide, adding a fat stain, and observing the number and size of fat globules that are present.
