Guest guest Posted October 24, 2002 Report Share Posted October 24, 2002 Caden's fecal fat was 4.5 grams per day. His diet was around 15 grams of fat per day. I do not have word from the GI Dr. yet. He actually doesn't even know that I have the test results. I just managed to get the results! Doesn't this seem high? The expected results are anywhere from 2-7 grams of fat per day for a 100gram diet. Does anyone know the formula for figuring up the fat retention coefficient? This 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. Thanks!

Guest guest Posted October 24, 2002 Report Share Posted October 24, 2002 Hi Krystena, maybe I don't understand your question, since I have no clue about the fecal fat test at all. But since I earn my living by computing percentages, I know at least this :-)) If you have given 15 grams fat per day and 4.5 grams have been found in the stool again, then the retention rate should be 70%. 1.5 gram are ten percent, 4.5 are three times that high. Hope this answers your question. I have never heard of measuring enzymes content. Here in Germany you measure the content of elastase to find out whether a pwcf is pancreatic sufficient or not. If you only measure the amount of enzymes as your GI has done, you can't determine whether the enzymes are produced in the pancreas or somewhere else. That's why the elastase test is more specific to check for pancreas activity. Here is the US homepage of the company that offers the test. http://www.usa.schebo.com/gastro/en/stadvan.html Peace Torsten, dad of Fiona 5wcf e-mail: torstenkrafft@...
