Reference Range

Test	Reference range	Units	Interpretation
Cholesterol	0 - 199	mg/dL	<200 is desirable; 200-239 is borderline/high; >240 is high
Triglyceride	0 - 149	mg/dL
HDL	40 - 60	mg/dl
LDL Calculated or Direct	0 - 129	mg/dL	Evaluation of cardiovascular risk is based on the following range of values: Desirable: <100 mg/dL Low risk: 100-129 mg/dL Borderline high: 130-159 mg/dL High: 160-189 mg/dL Very high: > or =190 mg/dL Reference: Executive Summary of the Third Report of the National Cholesterol Education Program (NCEP) Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel III), JAMA 2001;285:2486-2497

Clinical Significance

In a standard lipid panel, the LDL value is calculated based on the concentrations of total cholesterol, HDL cholesterol, and triglycerides. At triglyceride concentrations above 300 mg/dL, the calculated LDL is inaccurate. In such cases, it is appropriate to measure LDL directly.
