Overview of Lipid Profile

What is Lipid Profile?

Lipids are fat or fat like biomolecules that form one of the major structural components of the cells, apart from playing essential roles in cell signaling or communication between cells. Lipids also acts as a source and mode of storage of energy for the body. The Lipid Profile Test measures the levels of specific types of lipids in blood.

Sample Type

The sample type collected for Lipid Profile is: Blood

Preparation for Lipid Profile

  • Do not eat or drink anything other than water for 8-12 hours before the test.

Why Get Tested for Lipid Profile?


The Lipid Profile Test is performed:

·         To screen for risk of development of cardiovascular diseases

·         To monitor patients who have one or more risk factors for development of cardiovascular diseases

·         To monitor patients who have shown undesirable results in a previous Lipid Profile Test

·

        

To monitor efficacy of treatment



Understand more about Lipid Profile


Lipids are fatty acids playing essential roles in cellular structure, cell signaling, and as energy storage for the body. Cholesterols and triglycerides are essential lipids which are transported in blood by lipoprotein particles made up of cholesterol, triglycerides, proteins and phospholipid molecules. The lipoprotein particles are classified according to their densities into High Density Lipoproteins (HDL), Low Density Lipoproteins (LDL), and Very Low Density Lipoproteins (VLDL).


Cholesterol is a fat like substance which is formed in the liver, as well as obtained from dietary sources. It is found in all cells and is an essential part of the structural framework of the cells apart from performing various vital body processes. However, excess cholesterol is harmful. Increased cholesterol in blood can cause it to be deposited on the inner wall of the blood vessels forming plaque.


Triglycerides are the commonest type of fat in the body. Triglycerides are obtained from dietary sources and form the stored fat in adipose tissues. Increase in triglyceride concentration can also give rise to cardiovascular diseases.


High Density Lipoproteins or HDLs are particles of high density which help to reduce chances of cardiovascular diseases by picking up and carrying lipoprotein particles of lower density to the liver for disposal.


Low Density Lipoproteins or LDLs are lipoprotein particles of low density which carry cholesterol to the tissues. Cholesterol carried by LDLs easily come out of blood and gets deposited on the inner walls of blood vessels, increasing the chances of cardiovascular diseases.


Very Low Density Lipoproteins or VLDLs are lipoprotein particles of very low density which carry triglycerides to the tissues. Excess triglycerides in blood causes increase in VLDL particles which in turn again increase the chance of development of cardiovascular diseases.


Plaque deposition makes the lumen of the blood vessels narrower thereby preventing proper flow of blood and may stop the flow completely. Excessive plaque deposition can also cause the arteries to harden, giving rise to a condition called Atherosclerosis. Improper flow of blood prevents supply of nutrients and oxygen to the vital organs and may cause heart attack or stroke.


The Lipid Profile Test typically measures the levels of total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides. Other results that may be reported include VLDL cholesterol, non-HDL cholesterol, and total cholesterol to HDL cholesterol ratio.





What Results of Lipid Profile mean?

Interpretations


Higher than optimum levels of total cholesterol, LDL cholesterol, non HDL cholesterol, and fasting triglycerides indicate an increased risk of plaque formation in the blood vessels (atherosclerosis) and cardiovascular diseases, heart attack, or stroke.

HDL cholesterol reduces the risk factors of development of cardiovascular diseases. In absence of other factors, higher the HDL levels in blood, lower is the chance of development of cardiovascular diseases.




Patient Concerns about Lipid Profile

Frequently Asked Questions about Lipid Profile

Q. How is this test performed?
This test is performed on a blood sample. A syringe with a fine needle attached is used to withdraw blood sample from a blood vessel in your arm generally from the inner side of the elbow area. The doctor, nurse or the phlebotomist will tie an elastic band around your arm which will help the blood vessels to swell with blood and hence makes it easier to withdraw blood. You may be asked to tightly clench your fist. Once the veins are clearly visible, the area is cleaned with an antiseptic solution and then the needle is inserted into the blood vessel to collect the sample. You may feel a tiny pinprick during the procedure. Blood sample once collected is then sent to the laboratory.
Q. Is there any risk associated with this test?
There is no risk associated with the test. However, as this test involves a needle prick to withdraw the blood sample, rarely, a patient may experience increased bleeding, hematoma (blood collection under the skin) formation, bruising or infection at the site of needle prick.
