Lipoprotein Subfraction Analysis (Serum) – Quantitative Profile
This test measures specific types of fats (lipoproteins) in your blood, including cholesterol and triglycerides, to assess heart health and risk of cardiovascular disease.

Why This Test Is Done
Doctors may order this test to evaluate your risk of heart disease, monitor existing conditions like high cholesterol, or check for metabolic disorders. It’s often part of routine check-ups or follow-ups for conditions like diabetes or high blood pressure.
What to Expect Before the Test
No special preparation is needed, but you may be asked to fast for 12 hours before the blood draw. Your doctor will provide specific instructions if applicable.
How the Test Works
Blood is drawn from a vein, usually in your arm. The sample is then analyzed to separate and measure different lipoprotein types, including low-density lipoproteins (LDL), high-density lipoproteins (HDL), and very low-density lipoproteins (VLDL).
What the Results Mean
Results show the amounts of various lipoproteins, helping identify high or low levels that may affect heart health. Your doctor will interpret these results in the context of your overall health and medical history.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions
High levels of LDL or VLDL can increase the risk of plaque buildup in arteries, leading to heart disease or stroke. Low HDL may also raise risk. This test helps guide treatment plans, such as diet, exercise, or medication to improve lipid levels.
High levels of LDL or VLDL may signal an increased risk of cardiovascular issues, prompting lifestyle changes or medical interventions. Low HDL levels may also raise concerns, as HDL helps remove cholesterol from arteries. Your doctor will discuss these findings with you.
