About
Measures the proportion of fat in stool (steatocrit). Used to detect fat malabsorption (steatorrhea).
Preparation
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).
Beyond these general rules, preparation for some tests and diagnostic procedures may require specific instructions from your treating doctor.
