with an estimated 1.5 million heart attacks and 0.5 million strokes occurring annually, many in individuals
who have no prior symptoms. Prevention of ischemic cardiovascular events is key. Risk factors, including
age, smoking status, hypertension, diabetes, cholesterol, and high-density lipoprotein (HDL) cholesterol,
are used by physicians to identify individuals likely to have an ischemic event. The National Cholesterol
Education Program (NCEP) Adult Treatment Panel III (ATP-III) classified lipid results and established
guidelines for lipid testing and patient management.
Useful For: Evaluation of cardiovascular risk
Interpretation: Mayo Clinic has adopted the NCEP ATP III classifications, which are included as
reference values on Mayo Clinic and Mayo Medical Laboratories reports (see Reference Values).
Reference Values:
The National Cholesterol Education Program (NCEP) has set the following guidelines for lipids (total
cholesterol, triglycerides, HDL, and LDL cholesterol) in adults ages 18 and up:
TOTAL CHOLESTEROL
Desirable: or =240 mg/dL
TRIGLYCERIDES
Normal: or =500 mg/dL
HDL CHOLESTEROL
Low (removed HDL): 60 mg/dL
LDL CHOLESTEROL
Optimal: or =190 mg/dL
NON HDL CHOLESTEROL
Desirable: or =190 mg/dL
The National Cholesterol Education Program (NCEP) and National Health and Nutrition Examination
Survey (NHANES) has set the following guidelines for lipids (total cholesterol, triglycerides, HDL, and
LDL cholesterol) in children ages 2-17:
TOTAL CHOLESTEROL
Desirable: or =200 mg/dL
TRIGLYCERIDES
Normal: or =130 mg/dL
HDL CHOLESTEROL
