Interpretive Data
Neutral fats include the monoglycerides, diglycerides, and triglycerides while split fats are the free fatty acids that are liberated from them. Impaired synthesis or secretion of pancreatic enzymes or bile may cause an increase in neutral fats while an increase in split fats suggests impaired absorption of nutrients.
