Client Notes:  
Patient Preparation: If a cholesterol measurement is to be performed along with triglycerides, the patient should be fasting 9-12 hours prior to collection.

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.
