About the Cholesterol blood test
Measure the level of triglycerides, LDL, and HDL cholesterol in your blood and check your risk of heart disease based on your ratio of HDL good to total cholesterol.
LDL cholesterol can build up on your artery walls and hardens over time, narrowing the arteries and increasing your risk of heart disease. HDL cholesterol can help stop this by taking LDL cholesterol and passing it out through the liver. Healthy cholesterol levels should be low levels of LDL and high level of HDL cholesterol.
Triglycerides are the main source of fat in the body, which we all need but if its present in high levels then this increases the risk of heart disease

Biomarker information for Cholesterol blood test
Cholesterol is an essential fat (lipid) in the body. It has some important functions, including building cell membranes and producing a number of essential hormones such as testosterone and oestradiol. There are a number of different types of cholesterol, but the two main components of total cholesterol are HDL (high density lipoprotein) -“Good” and LDL (low density lipoprotein)- “Bad”.
The total cholesterol result on its own only shows the total amount of both of these components and so even if you have a good amount of total cholesterol, you may have a low amount of good cholesterol and high amount of bad cholesterol therefore its important to review each of these results to understand your cardiovascular health and risks of cardiovascular disease.
LDL cholesterol (low-density lipoprotein) is a molecule made of lipids and proteins which transports cholesterol, triglycerides and other fats to various tissues throughout the body. Too much LDL cholesterol, commonly called ‘bad cholesterol’, can cause fatty deposits to accumulate inside artery walls, potentially leading to atherosclerosis and heart disease.
HDL cholesterol (high-density lipoprotein) is a molecule in the body which removes cholesterol from the bloodstream and transports it to the liver where it is broken down and removed from the body in bile. HDL cholesterol is commonly known as ‘good cholesterol’.
Cholesterol in your body is generally broken down into 2 main components; HDL and LDL. However there are other types of cholesterol such as VLDL (very low-density lipoproteins) and other lipoproteins which are thought to be even more harmful than LDL cholesterol. Non-HDL cholesterol is calculated by subtracting your HDL cholesterol value from your total cholesterol. It therefore includes all the potentially harmful cholesterol in your blood including LDL. As such, it is considered to be a better marker for cardiovascular risk than total cholesterol and LDL cholesterol.
The cholesterol/HDL ratio is calculated by dividing your total cholesterol value by your HDL cholesterol level. It is used as a measure of cardiovascular risk because it gives a good insight into the proportion of your total cholesterol which is “good” (i.e. high-density lipoprotein, HDL). If your health check includes advanced cardiovascular risk scoring – QRisk then this value is important and used to help calculate your risk of having a heart attack.
Triglycerides are a type of fat (lipid) that circulate in the blood. After you eat, your body converts excess calories (whether from fat or carbohydrates) into triglycerides which are then transported to cells to be stored as fat. Your body then releases triglycerides when required for energy.
What does the Cholesterol blood test involve?
This blood test is just like a standard blood test.
You will be asked to uncover you left or right arm and suitable vein is found. A tourniquet will be placed and tightened around your upper arm allowing the veins to swell and a needle will be placed into your vein. A small quantity of blood is then drawn into tubes. Once the procedure is complete a small plaster will be placed onto the site which can be removed after a few hours.
How do I prepare
- The blood test requires access to the area of interest, therefore, it is recommended to wear loose clothing to facilitate this process.
- No specific preparation is required for this scan.
- We will require details of your GP / Health Care Professional, which may be requested before or at the time of the scan.
- Blood results require interpretation. All results should be interpreted by your regular health care professional / GP.
