Diabetes Risk Panel without Score

Test Code

91920

CPT Codes
80061, 82947, 83036

Includes

Glucose
Hemoglobin A1c
Lipid Panel: Total Cholesterol, HDL Cholesterol, Triglycerides, LDL-Cholesterol (calculated), Cholesterol/HDL Ratio (calculated), Non-HDL Cholesterol (calculated)

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

Preferred Specimen

3 mL serum collected in a serum separator tube (SST®) and 1 mL whole blood collected in an EDTA (lavender-top) tube

Patient Preparation
Patient should fast 9-12 hours prior to collection. Fasting required. Fasting is defined as no consumption of food or beverage other than water for at least 8 hours before testing.

Minimum Volume

1 mL serum • 0.5 mL whole blood

Instructions

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.
If an HDL cholesterol measurement is to be performed along with triglycerides, the patient should be fasting 9-12 hours prior to collection.

Clinical Significance

To assist with control of blood glucose levels, the American Diabetes Association (ADA) has recommended glycated hemoglobin testing (HbA1c) twice a year for patients with stable glycemia, and quarterly for patients with poor glucose control. Interpretative ranges are based on ADA guidelines.
