HDL (high density lipoprotein) cholesterol, also known as high density lipoprotein, is a type of blood fat, which is transported bound to proteins in plasma. As a result, it is largely made up of proteins, cholesterol, and small amounts of triglycerides. HDL cholesterol is also called “good” cholesterol because it removes excess cholesterol (which is not taken up by cells) as well as cholesterol deposits in and around the vessel wall. Excess cholesterol and its accumulations are transported to the liver, where some of them are excreted with the bile. In this way, HDL cholesterol helps clean the walls of blood vessels and also protects our body from atherosclerosis.
What does the test show?
HDL-cholesterol level can be an indicator of the development of cardiovascular diseases and help monitor diseases associated with lipid metabolism.
In which cases is it recommended to perform the test?
HDL cholesterol is usually tested along with other items (cholesterol, LDL cholesterol, triglyceride). It is recommended to measure its level in a healthy body, as its value is temporarily low during and after illnesses.
What sample is needed for the test?
A blood sample taken from a vein is needed for the test.
What can the result indicate?
The lower the level of HDL cholesterol, the greater the risk of developing cardiovascular disease (atherosclerosis, stroke, myocardial infarction) is.
What to do after the test?
The test alone cannot diagnose any disease, and in all cases consult an internist or haematologist to determine the exact diagnosis and necessary therapy.
