Very Low Density Lipoprotein

Other names: VLDL

Very low dentistry lipoprotein (VLDL) is one of three forms of lipoprotein; the other two include high density lipoprotein (HDL) and low density lipoprotein (LDL). Each particle of lipoprotein contains component parts including triglycerides, cholesterol and protein; the different forms of lipoprotein have varying amounts of each component part. VLDL has high triglyceride content. VLDL particles are released into the bloodstream by the liver; they are eventually broken down into low density lipoproteins.

When is the test used?

The test is used as part of a panel of tests, known as the lipid profile, to asses risk of heart disease and vascular conditions. The test may also be used to help with the diagnosis of a rare condition known as familial dysbetalipoproteinaemia.

The test is usually ordered to assess an individual’s risk of coronary heart disease or vascular disease but it may also be ordered when a doctor suspects that a patient has symptoms of familial dysbetalipoproteinaemia.

How is the test performed?

The test is done by collecting a sample of blood from a vein the patient’s arm; a needle is inserted into the vein and the blood is drawn out and collected in a syringe. When the nurse or doctor has a sufficient sample, the blood is bottled, labelled and sent to the laboratory for evaluation.

What do the test results mean?

If the test results show high levels of VLDL this indicates a high risk of heart disease and vascular disease; a doctor may suggest that the patient changes their diet, exercise regime and lifestyle choices and they may start them on a course of treatment.

The test result may also help to diagnose familial dysbetalipoproteinaemia; if the ratio of VLDL cholesterol to total triglyceride is more than 0.3, this may indicate that the patient has the disease.
