Clinical Information

Triglycerides are a family of lipids absorbed from the diet and produced endogenously from carbohydrates and fatty acids. Measurement of triglyceride is important in the diagnosis and management of hyperlipidemia. These diseases can be genetic or secondary to other disorders including nephrosis, diabetes mellitus, and endocrine disturbances.

 

The National Cholesterol Education Program (NCEP) cites evidence that triglycerides are an independent risk factor for atherosclerosis. Individuals with hypertension, obesity, and/or diabetes are at a greater risk than those without these conditions. The Adult Treatment Panel of the NCEP recommends that all adults 20 years of age and over should obtain a fasting lipoprotein profile once every five years to screen for coronary heart disease.
