Fecal Steatocrit (Free Fat)

Ideally follow a diet with no more than 70-100 g of fat per day for at least 3 days before the test. For 72 hours before stool collection, avoid laxatives, rectal suppositories and oils, and limit (as agreed with your doctor) medications that affect bowel motility (belladonna, pilocarpine, etc.) and stool color (iron, bismuth, barium sulfate).
