Serum increases in triglyceride (TG) and turbidity (TB) after fat test meal were measured in 3 groups of children: 43 controls, 27 with untreated celiac disease and 62 with cystic fibrosis. Percentage increases over 21.4% of serum TG (120 minutes after the test meal) were found in normal subjects. Smaller increases of serum TG were found in celiac (81.4%) and CF (83.4%) patients. The combination of the TG test and the 1-hour D-xylose test resulted in abnormality of at least one test in 100% of the celiac patients with subtotal atrophy of intestinal mucosa. In contrast with the serum turbidity (TB) test, the TG test is rapid, simple, of no discomfort to children and is accurate and sensitive in the diagnosis of intestinal malabsorption.

Abstract
Serum increases in triglyceride (TG) and turbidity (TB) after fat test meal were measured in 3 groups of children: 43 controls, 27 with untreated celiac disease and 62 with cystic fibrosis. Percentage increases over 21.4% of serum TG (120 minutes after the test meal) were found in normal subjects. Smaller increases of serum TG were found in celiac (81.4%) and CF (83.4%) patients. The combination of the TG test and the 1-hour D-xylose test resulted in abnormality of at least one test in 100% of the celiac patients with subtotal atrophy of intestinal mucosa. In contrast with the serum turbidity (TB) test, the TG test is rapid, simple, of no discomfort to children and is accurate and sensitive in the diagnosis of intestinal malabsorption.
