Lipid Panel: C906 (includes Total Cholesterol, HDL Cholesterol, Triglycerides, Calculated LDL Cholesterol, Cholesterol/HDL-C, Non-HDL Cholesterol)
Lipid Panel and Direct LDL Cholesterol Reflex: C909 (includes Total Cholesterol, HDL Cholesterol, Triglycerides, Calculated LDL Cholesterol, Cholesterol/HDL-C, Non-HDL Cholesterol). If Triglycerides are greater than 400 mg/dL, then Direct LDL Cholesterol will be performed at an additional charge (CPT 83721).
Refer to individual tests for assay information.

Clinical Significance: The lipid panel is used, along with other tests, during routine assessment to determine an individual’s risk of cardiovascular disease. A lipid panel can also be used to monitor the efficacy of lifestyle interventions or medications.
Limitations: Patients treated with N-Acetyl Cysteine (NAC) for acetaminophen overdose may generate a false low result for cholesterol. Venipuncture immediately after or during the administration of Metamizole (Dipyrone) may lead to falsely low results for cholesterol and triglyceride. Venipuncture should be performed prior to the administration of Metamizole. In very rare cases gammopathy, especially monoclonal IgM (Waldenstrom’s macroglobulinemia), may cause unreliable results.
