About Ldl subfractions

What are LDL subfractions?

Cholesterol is a type of lipid (fat) which is essential for healthy cellular metabolism. Cholesterol forms complexes with triglycerides, phospholipids and apolipoproteins to form lipoproteins, which transport fat and cholesterol around the body through lymph, blood and cerebrospinal fluid.

Different types of lipoprotein are formed depending on the apolipoproteins they are primarily made from, affecting how they are transported and processed by the body. Low-density lipoprotein (LDL) or ‘bad cholesterol’ transports cholesterol to different tissues around the body. where it can cause fatty build-up in excessive quantities, increasing the risk of cardiovascular disease.

LDL consists of several different sub-categories with different characteristics, known as subfractions. Which subfractions are present in different ratios affects the risk of disease with small, dense LDLs thought to increase risk over larger ones.

Why take the test?

This test measures the different subfractions of LDL in the body. It is used to give detailed information on the cholesterol level in the body as a measure of the risk of cardiovascular disease.
