About the test
LDL cholesterol is a low density lipoprotein which transfers cholesterol from the liver to other organs.
It is also known as “bad” cholesterol as it contributes to the formation of atheromatous plaque, increasing thus the risk for cardiovascular disease.

Additional information
- Based on their density, lipoproteins are classified as chylomicrons, very low density lipoproteins (VLDL), intermediate density lipoproteins (IDL), low density lipoproteins (LDL) and high density lipoproteins (HDL).
- LDL can be decreased by adopting a healthy way of life or by medical treatment.
