Additional Information

To convert mg/dL to mmol/L (SI units) multiply by 0.0259.

LDL cholesterol is calculated from the formula: Total cholesterol-(HDL cholest. + Triglycerides/5). THIS ESTIMATE IS NOT RELIABLE IF TRIGLYCERIDES EXCEED 400 mg/dL, at which level the calculation of LDL cholesterol is suppressed and an explanatory comment is appended. To obtain a more reliable estimate of LDL cholesterol in this situation, request sendout testing for direct LDL assay.

The strict requirement of a fasting sample for lipid analysis is no longer considered necessary by many authorities. Changes in CV risk management guidelines, and the results of studies comparing fasting to non-fasting lipid levels, indicate that fasting samples need not be routinely required.
