2 mL serum

Patient Preparation
For optimum results, the patient conditions at the time of sample collection should be:
a. Following a stable diet for at least a week.
b. Stable body weight.
c. Fasting for at least 12 hours (12 to 16 hours)

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 and 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.
