Stool Fat Test 
This test requires a 72-hour stool collection. The patient should abstain from alcohol during this time and maintain a high-fat diet (100 g/day) for three days before the test, and during the collection period. The patient should call the laboratory for instructions on how to collect the specimen.
Normal results
Reference values vary from laboratory to laboratory, but are generally found within the range of 5-7 g/24 hr.
It should be noted that children, especially infants, cannot ingest the 100 g/day of fat that is suggested for the test. Therefore, a fat retention coefficient is determined by measuring the difference between ingested fat and fecal fat, and expressing that difference as a percentage. The figure, called the fat retention coefficient, is 95% or greater in healthy children and adults. A low value is indicative of steatorrhea.

糞便脂肪定量為脂肪痢的confirm test

每天攝取含100g脂肪的標準飲食，至少要收集三天的糞便
正常兒童及成年人的脂肪保留係數至少要大於95%才是正常
（脂肪保留係數＝(食入脂肪-糞便脂肪)/食入脂肪）
