Test Code LABLIPDR Lipid Panel with Reflex to Measured LDL

Clinical Information

This panel is useful in the evaluation of risk for atherosclerotic cardiovascular diseases. The reported LDL is calculated using the Friedwald equation, (c)LDL = T CHOL- HDL - (TRIG/5). Note, the Friedwald equation cannot be used when triglycerides exceed 400 mg/dL; in these cases, a direct LDL measurement with reflex. Fasting samples are preferred but not required unless directed by the ordering provider.

Cautions

Gross hemolysis causes falsely elevated total cholesterol results. Icteric specimens may produce unreliable total cholesterol and direct LDL results.
