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:

LDL CHOLESTEROL

Desirable: <100 mg/dL

Above Desirable: 100-129 mg/dL

Borderline High: 130-159 mg/dL

High: 160-189 mg/dL

Very High: ≥190 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:

 

LDL CHOLESTEROL

Acceptable: <110 mg/dL

Borderline High: 110-129 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 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.

 

Low-density lipoprotein cholesterol results of 190 mg/dL or above in adults (≥160 mg/dL in children) are severely elevated and may indicate familial hypercholesterolemia.
