Understand your cholesterol test results
Use this page to understand your cholesterol and triglyceride results and see if they are in the healthy range.
When you have a cholesterol test, ask your healthcare professional to explain the results, so you don't have any unnecessary worry or confusion.
It’s not just your total cholesterol that’s important, so your results will include different types of cholesterol. If you are only given your total cholesterol, ask for a break-down of the other numbers – it’s possible to have a healthy total cholesterol (TC) number but an unhealthy balance of the different types of cholesterol.
Ask for a print out of your results if you are not able to speak to your GP, nurse or pharmacist.
What should your results include?
As a minimum, you should be given your total cholesterol (TC) and HDL (good cholesterol), then you can work out your ratio of total cholesterol to HDL cholesterol (written as the TC:HDL ratio).
You might also have your triglycerides tested, these are another type of blood fat which are linked to heart disease.
-
Total cholesterol
This is sometimes written as 'serum cholesterol' or 'TC' and refers to your overall level of cholesterol. -
Non-HDL cholesterol
Your non-HDL cholesterol is your total cholesterol minus your HDL cholesterol. It’s all the 'bad' cholesterol added together, including your LDL cholesterol. Ideally it should be as low as possible.
-
HDL cholesterol
Your HDL cholesterol ('good' cholesterol) helps clear the cholesterol out of your arteries, while your LDL cholesterol ('bad' cholesterol) can clog them up. Your HDL cholesterol should ideally be high, around 1.4mmol/L, but our specialists believe that HDL levels higher than this might not give you any extra benefit. -
TC:HDL ratio
You might be given a TC:HDL ratio, which is the ratio of HDL compared to the total cholesterol. If not, you can work it out by a simple division: total cholesterol divided by HDL cholesterol. This should be as low as possible. Above 6 is considered high. - The TC:HDL ratio should not just be looked at on its own, but alongside all the other "numbers" i.e. it is important to look at both the HDL cholesterol and non HDL cholesterol, even if the TC:HDL ratio is low
What is a healthy cholesterol level?
This table is a general guide for ideal cholesterol and triglyceride levels for healthy adults in the UK. If you have a condition such as heart disease or diabetes, your target levels may be lower – your doctor will be able to tell you your individual targets.
| mmol/L | mg/dL | |
| Total (serum) cholesterol | below 5.0 | below 193 |
| Non-HDL cholesterol | below 4.0 | below 155 |
| LDL cholesterol | below 3.0 | below 116 |
|
HDL cholesterol
|
above 1.0 for a man above 1.2 for a woman (ideally around 1.4. Very high levels may not give extra protection) |
above 39 for a man above 46 for a woman |
| TC:HDL ratio | Above 6 is considered high risk - the lower this figure is the better | Above 6 is considered high risk - the lower this figure is the better |
Triglycerides are another type of blood fat and your triglyceride levels can tell you more about your health. If your triglycerides are high, it can mean you’re at risk of heart disease, liver disease and diabetes.
You might have your triglycerides tested when you have a cholesterol test.
What can raise your triglycerides?
Raised triglycerides and low HDL cholesterol
People with high triglyceride levels often have a low HDL level as well, which is an unhealthy combination that's often linked with premature heart disease. It can be inherited and often occurs in people who carry their weight around their middle.
What is a healthy triglyceride level?
As a general rule, these are the ideal triglyceride levels for healthy adults. Fasting triglycerides are where you fast for a period of time before your blood test, usually 10-14 hours.
| Fasting triglyceride | below 1.7mmol/L | below 150mg/dL |
| Non-fasting triglyceride | below 2.3mmol/L | below 204mg/dL |
Converting from mmol/l to mg/dl
In the UK, cholesterol levels are measured in millimoles per litre (mmol/l). If you have your cholesterol tested in Europe or the US, they will be measured in milligrams per deciliter (mg/dl). Here’s how to convert from one to the other:
To convert cholesterol levels:
Cholesterol mg/dl = mmol/l x 38.6
Cholesterol mmol/l = mg/dl ÷ 38.6
To convert triglyceride levels:
Triglyceride mg/dl = mmol/l x 88.5
Triglyceride mmol/l = mg/dl ÷ 88.5
Cholesterol levels for men and women
HDL levels differ for men and women
Women naturally have higher HDL cholesterol (good cholesterol) levels than men due to differences in the genes. Women should aim for an HDL cholesterol level above 1.2mmol/L while men should aim for above 1mmol/L.
Cholesterol levels can rise during pregnancy
During pregnancy, both cholesterol and triglyceride levels can significantly rise. We don't recommend getting a cholesterol test during pregnancy because your results won't be accurate. Our advice is to wait until at least 6-8 weeks after your baby is born or after you stop breastfeeding to get a cholesterol test. This means you don't need to worry unnecessarily.
Cholesterol levels rise during the menopause
Women may also find their cholesterol levels rise during the menopause.
Do you need to lower your cholesterol and triglycerides?
If you have high cholesterol, high triglycerides or an unhealthy balance of blood fats, your doctor will probably recommend bringing these levels down with lifestyle changes and sometimes treatments.
Your doctor should look at your results in relation to any other risk factors for heart disease such as high blood pressure, being overweight, smoking, and other health conditions such as diabetes.
If you are at higher risk or already have cardiovascular disease, for example if you have already had a heart attack, stroke or TIA, or have peripheral vascular disease, you should already be on cholesterol-lowering medication such as statins. In the UK, guidelines recommend lowering your non-HDL cholesterol ("bad cholesterol") by at least a 40%. If your current non-HDL level is not known, then the guideline is to aim for below 2.5mmol/L (or LDL cholesterol below 1.8mmol/L).
Find out your heart age with the Heart Age Tool
Once you have your cholesterol results, you can work out your risk of developing heart disease over the next 10 years with the NHS Heart Age Tool. You will get a more accurate result if you know your blood pressure numbers too.
The heart age tool is designed for people aged 25 to 84. It's not suitable for you if you already have a cardiovascular disease such as heart attack or stroke, or an inherited high cholesterol condition such as Familial Hypercholesterolaemia (FH).
Adults age 40-74 are also invited for NHS Health Checks which includes other simple tests to look at your heart health.
