About the Test

Total cholesterol testing can help assess your risk for cardiovascular diseases, monitor existing conditions, or evaluate the effects of medications. This cholesterol test measures the total amount of cholesterol content in your blood based on your LDL (bad cholesterol) and HDL (good cholesterol) levels. High levels of LDL cholesterol in your blood may cause a buildup of fatty deposits in your arteries, which reduces blood flow. HDL cholesterol helps carry away LDL cholesterol while keeping your arteries open and allowing for blood to flow more freely. Too much cholesterol in your blood may damage arteries and blood vessels, which may increase the risk for stroke, heart attack, and heart disease.

This test will only provide a value for total cholesterol and not individual values for LDL or HDL.

Buy your own total cholesterol test online with Quest. No doctor’s visit is required – simply purchase cholesterol testing, visit a nearby Quest® location for sample collection, and get fast results.

This test may be helpful for those who:

Have never checked total cholesterol levels or haven't checked them in several years
Have a family history of high cholesterol or heart disease
Have high blood pressure
Have diabetes
Are overweight or obese
Eat a diet high in fat, processed foods, or sugar
Don't get enough physical activity
Smoke or use tobacco

Cholesterol is a waxy, fatty substance found in the blood and is needed to make cell walls, tissues, hormones, vitamin D, and bile acid. Cholesterol comes from internal and external sources. The liver is responsible for creating cholesterol within the body and it provides all that you need. The remainder of the cholesterol in your body comes from animal-based foods like meat, poultry, and dairy products. Too much cholesterol in the blood may clog blood vessels, which reduces the flow of blood to the heart, brain, and other organs. This may increase your risk of heart disease, stroke, and other serious health conditions.

Cholesterol travels through the bloodstream on particles made of protein and fat (lipoproteins). High-density lipoprotein (HDL) and low-density lipoprotein (LDL) are 2 types of lipoproteins. HDL is known as “good cholesterol” because it transports cholesterol away from cells and tissues to the liver, where it is eventually removed from the body. This helps lower blood cholesterol levels. LDL is known as “bad cholesterol” because it carries fatty deposits (plaques) toward the arteries. A high amount of LDL in the blood may cause cholesterol to accumulate in the vessel walls, resulting in plaque buildup and narrowing of the arteries, a condition known as atherosclerosis. Our Total Cholesterol Test combines your HDL and LDL levels, representing your total cholesterol number. This helps determine whether your cholesterol is elevated.

This test will only provide a value for Total Cholesterol and not individual values for LDL or HDL.

FAQs

How does liver disease affect cholesterol levels?

An important function of the liver is the production and elimination of cholesterol. If your liver is damaged or not functioning properly, cholesterol can build up, causing fatty liver disease, which can increase your risk of diabetes or stroke.

Is there a connection between thyroid and cholesterol levels?

The thyroid gland has a direct impact on cholesterol levels. Individuals living with low thyroid function (hypothyroidism) may have higher cholesterol levels than those with normal thyroid function. This is because thyroid hormones help the liver break down and eliminate cholesterol. If the thyroid isn’t functioning properly, it may cause a buildup of LDL in your blood. Thyroid hormone treatment may result in a reduction of total cholesterol levels.
