Serum or Plasma Complex Lipid Profile (Including Specific Lipoprotein Subfractions)

What This Test Measures

The test includes measurements for total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and various lipoprotein subfractions (such as very-low-density lipoproteins, intermediate-density lipoproteins, and lipoprotein(a)). Some tests may also evaluate triglycerides and specific lipid ratios.

Why It Matters for Your Health

High levels of certain lipoproteins or cholesterol can increase your risk of heart disease, stroke, or other cardiovascular conditions. This detailed profile helps doctors identify imbalances that may require lifestyle changes or medical treatment.

Sample Collection and Preparation

A blood sample is drawn from a vein, usually in your arm. The blood is then processed to separate serum (if drawn without an anticoagulant) or plasma (if drawn with an anticoagulant like EDTA). The sample is sent to a lab for analysis using advanced techniques like high-performance liquid chromatography (HPLC) or immunoassay methods.

Common Uses and Recommendations

Doctors may order this test to monitor cholesterol levels, evaluate risk for heart disease, diagnose metabolic disorders, or assess treatment effectiveness in patients with known lipid disorders.
