[Intestinal absorption of fats in children using serum turbidity and triglyceride absorption tests]

Intestinal fat absorption was studied, using serum turbidity and serum triglyceride levels, which were determined before and after a test meal of 2 g neutral fat per kg b.w. in 33 children: 25 controls, four with cystic fibrosis, and four with celiac disease. The results proved that the easy-to-perform serum turbidity test was superior to the triglyceride absorption test in characterizing fat digestion and absorption. The most substantial increase in both tests occurred about three hours after the oral fat load.
