Advanced Lipid Panel, Cardio IQ®

Test Code

92145

CPT Codes
80061, 83704, 82172, 83695

Includes

Cardio IQ® Cholesterol, Total; Cardio IQ® HDL Cholesterol; Cardio IQ® Triglycerides; Cardio IQ® Non-HDL and Calculated Components; Cardio IQ® Lipoprotein Fractionation, Ion Mobility; Cardio IQ® Apolipoprotein B; Cardio IQ® Lipoprotein (a)

If Triglyceride is >400 mg/dL, then Cardio IQ® Direct LDL will be performed at an additional charge (CPT code: 83721).

If Triglyceride is extremely elevated, >1293 mg/dL, this causes interference in the Cardio IQ® Direct LDL assay, therefore this test cannot be added.

Preferred Specimen

3 mL serum AND 1 mL serum

Patient Preparation
If a Cholesterol measurement is to be performed along with Triglycerides, but not part of a Lipid Panel, then the patient should be fasting 9-12 hours prior to collection. If the Cholesterol is ordered as part of a Lipid Panel, then a fasting sample is not required.

Minimum Volume

1.75 mL AND 0.25 mL

Instructions

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 hours and a third dose of 100 mg/kg administered over 16 hours.
