Cholesterol - Total

A Cholesterol - Total test measures the total amount of cholesterol (fats) in the blood. This test analyzes the risk of developing heart disease and monitors the effectiveness of any ongoing cholesterol-lowering treatment. It is often done as part of a lipid profile, which measures different types of fats in the blood.

Cholesterol is a waxy, fat-like substance found in all body cells. An optimal amount of cholesterol is essential for various bodily functions. However, too much cholesterol can build up in the blood vessels and increase the risk of heart disease, stroke, or other health problems. 

A Cholesterol - Total checks for low-density lipoprotein (LDL), also called ‘bad’ cholesterol, and high-density lipoprotein (HDL), also called ‘good’ cholesterol. Deposition of too much LDL cholesterol can narrow down or block the opening of blood vessels, making it harder for the blood to flow through, thereby increasing the risk of heart disease or other health problems. Whereas deposition of too much HDL cholesterol is usually considered beneficial for heart health, as it helps reduce the risk of plaque buildup in the blood vessels.

Usually, overnight fasting of 8 to 12 hours is preferred for a Cholesterol - Total. However, you can drink water during the fasting period. Also, your doctor may suggest you stop taking certain medications such as statins, beta-blockers, etc., a few days before this test, as these could affect your test results. 

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. The results will help them determine your medical condition, make recommendations for lifestyle modifications such as diet and exercise, decide whether or not medication will be required to manage your condition and formulate an overall treatment plan.
