Lipid Panel with Reflex to Direct LDL : 14852

Test Code

LIPRAU or 14852

Alias/See Also

Non-fasting Lipid Panel with Reflex

CPT Codes
80061

Includes

Cholesterol, Total; Triglycerides; HDL Cholesterol; LDL-Cholesterol (calculated); Cholesterol/HDL Ratio (calculated); Non-HDL Cholesterol (calculated); If Triglyceride result is >400 mg/dL, then Direct LDL will be performed at an additional charge (CPT code(s): 83721). (If reflex: 8293 LDLAU)

Instructions

Fasting is not required prior to collection of a lipid panel.

The assay manufacturer Beckman Coulter advises: "N-Acetyl Cysteine (NAC), when administered in therapeutic concentrations (for the treatment of acetaminophen overdose), has been. . . determined to interfere with assays for. . . cholesterol, uric acid" where "NAC interference may lead to falsely low results." According to Beckman Coulter, the NAC interference should be insignificant by 12 hours after completion of the initial loading dose of an IV infusion treatment regimen consisting of an initial loading dose of 150 mg/kg administered over 1 hour, a second dose of 50 mg/kg administered over 4 hrs and a third dose of 100 mg/kg administered over 16 hrs.

Clinical Significance

The Lipid Panel with Reflex to Direct LDL panel includes evaluation of total cholesterol, HDL-cholesterol, triglyceride (TG), LDL-cholesterol (calculated), cholesterol/HDL ratio (calculated), and non-HDL cholesterol; direct LDL-C measurement will be performed at additional cost if the TG level is >400 mg/dL. This panel is useful in the detection, classification, and monitoring of hyperlipidemia, especially those expected to have highly elevated TG levels.
