Test Overview
Enzymatic Colorimetric
Evaluation of cardiovascular risks, diagnosis of hypobetalipoproteinemia, and diagnosis of abetalipoproteinemia.
< or = 130 mg/dL. The National Cholesterol Education Program (NCEP) has set the following guidelines for serum LDL Cholesterol (ATP III Classification): Optimal <100 mg/dL; Near Optimal: 100 - 129 mg/dL; Borderline High 130 - 159 mg/dL; High 160 - 189 mg/dL; Very High >190 mg/dL. Patient's individual LDL-cholesterol goal may differ based on the presence of risk factors for cardiovascular disease.
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Additional Information
Note that a calculated LDL level (LDLC) is included with the LIPID Profile. The direct LDL Cholesterol level (DLDL) will be performed automatically at an additional charge if the Triglyceride level is greater than 400 mg/dL and less than 3000 mg/dL.
