1 hour (upon receipt in laboratory)
Reference Range:

<130 mg/dL (Approved by NCEP, National Cholesterol Education Program for adults 18 years and older)

Normal - <100 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: > or =130 mg/dL

 

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

Comments:

Fasting for at least 8 hours prior to collection is recommended. Cholesterol, Triglyceride and HDL Cholesterol must all be ordered for the Calculated LDL to be completed. The LDL Calculation cannot be done if Triglyceride value > 400 mg/dL. EDTA plasma causes decreased values.
