&lt;h2&gt;&lt;span style=&quot;color: #ff99cc;&quot;&gt;&lt;strong&gt;OVERVIEW&lt;/strong&gt;&lt;/span&gt;&lt;/h2&gt;
&lt;p&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Total fecal lipids include glycerides, phospholipids, glycolipids, soaps, sterols, cholesteryl esters, and sphingolipids. High levels of fecal fat (steatorrhea) suggest malabsorption disorders such as pancreatic insufficiency or Whipple disease. This measurement helps diagnose conditions affecting the pancreas (e.g., cystic fibrosis, chronic pancreatitis) and the intestines (e.g., Whipple disease, celiac disease). Although differentiating free fatty acids from neutral fats was once common in diagnosing pancreatic diseases, this method is now less preferred. Additionally, fecal fat composition may change with orlistat use, primarily shifting to neutral fatty acids and potentially affecting diagnostic accuracy.&lt;/span&gt;&lt;/p&gt;

&lt;li style=&quot;font-weight: 400;&quot;&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Patient should be on a fat-controlled diet (100-150 g fat per day).&lt;/span&gt;&lt;/li&gt;
&lt;li style=&quot;font-weight: 400;&quot;&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;No laxatives (particularly mineral oil and castor oil).&lt;/span&gt;&lt;/li&gt;
&lt;li style=&quot;font-weight: 400;&quot;&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;No synthetic fat substitutes (eg, Olestra) or fat-blocking nutritional supplements.&lt;/span&gt;&lt;/li&gt;
&lt;li style=&quot;font-weight: 400;&quot;&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;The use of diaper rash ointments will falsely elevate test results. Discontinue use during collection period.&lt;/span&gt;&lt;/li&gt;
&lt;li style=&quot;font-weight: 400;&quot;&gt;&lt;span style=&quot;color: #99ccff;&quot;&gt;Barium interferes with test procedure; a waiting period of 48 hours before stool collection analysis is recommended.&lt;/span&gt;&lt;/li&gt;
