Reference Values

The National Lipid Association and the National Cholesterol Education Program have set the following guidelines for lipids in a context of cardiovascular risk for adults 18 years old and older:

TRIGLYCERIDES

Normal: <150 mg/dL

Borderline High: 150-199 mg/dL

High: 200-499 mg/dL

Very High: ≥500 mg/dL

 

The Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents has set the following guidelines for lipids in a context of cardiovascular risk for children 2 to 17 years old:

TRIGLYCERIDES

2-9 years:

Acceptable: <75 mg/dL

Borderline High: 75-99 mg/dL

High: ≥100 mg/dL

10-17 years:

Acceptable: <90 mg/dL

Borderline High: 90-129 mg/dL

High: ≥130 mg/dL

Reference values have not been established for patients who are younger than 24 months of age.

Interpretation

Maintaining desirable concentrations of lipids lowers atherosclerotic cardiovascular disease (ASCVD) risk. Establishing appropriate treatment strategies and lipid goals require that blood lipid values be considered in context with other risk factors including, age, sex, smoking status, and medical history of hypertension, diabetes, and cardiovascular disease.

 

Triglycerides results of 500 mg/dL and above are severely elevated, increasing the risk of pancreatitis.

 

Triglycerides can be lowered by increasing physical activity, low-fat diet, weight loss, and/or triglyceride lowering pharmaceuticals.
