Measurement of triglycerides as part of lipoprotein profiling
Triglycerides are esters of the trihydric alcohol, glycerol, with 3 long-chain fatty acids. They are partly synthesized in the liver and partly derived from the diet.
Only orderable as part of a profile. For more information see LMPP / Lipoprotein Metabolism Profile, Serum.
Triglycerides
2-9 years:
Acceptable: <75 mg/dL
Borderline high: 75-99 mg/dL
High: > or =100 mg/dL
10-17 years:
Acceptable: <90 mg/dL
Borderline high: 90-129 mg/dL
High: > or =130 mg/dL
> or =18 years:
Normal: <150 mg/dL
Borderline high: 150-199 mg/dL
High: 200-499 mg/dL
Very high: > or =500 mg/dL
Reference values have not been established for patients younger than 2 years.
Increased plasma triglyceride levels are indicative of a metabolic abnormality and, along with elevated cholesterol, are considered a risk factor for atherosclerotic disease. Hyperlipidemia may be inherited or be associated with biliary obstruction, diabetes mellitus, nephrotic syndrome, kidney failure, or metabolic disorders related to endocrinopathies. Increased triglycerides may also be associated with alcohol consumption, sedentarism or medication-induced (eg, prednisone).
Since cholesterol and triglycerides can vary independently, measurement of both is more meaningful than the measurement of cholesterol only.
Triglyceride result can be falsely decreased in patients with elevated levels of N-acetyl-p-benzoquinone imine (a metabolite of acetaminophen), N-acetylcysteine, and metamizole.

Samples analyzed for triglycerides are measured by an automated enzymatic method. The chemistry includes hydrolysis of the triglycerides and phosphorylation of the resulting glycerol.(Package insert: Triglycerides Reagent. Roche Diagnostics; V13.0, 03/2022)
