LIPID PANEL w/RFLX TO LDL DIRECT

Message

Test Code

LAB8544

CPT Codes
80061, 83721 (if direct LDL needed)

Includes

1.) Triglyceriders
2.) Total Cholesterol
3.) HDL Cholesterol
4.) LDL (Calculated)
5.) CHOL/HDL Ratio
6.) Non HDL
7.) VLDL

Note: LDL is calculated based on the Friedewald equation (LDL= Total Cholesterol - HDL Cholesterol - (Triglycerides/5)). This calculation is used when Triglycerides values are <400 mg/dL. For Triglycerides >400 mg/dL, a direct LDL measurement will be performed.

Clinical Significance

Lipids are important part of cells and tissues, and they help keep human body working normally. However, lipid disorders, such as high cholesterol, may lead to life-threatening illnesses, such as coronary artery disease (CAD), heart attack, or stroke
