What it measures
- Total cholesterol
- HDL cholesterol
- LDL cholesterol
- Triglycerides
- Cholesterol to HDL ratio
What is a lipid profile?
A lipid profile measures the fats in your blood:
- LDL cholesterol (“bad” cholesterol) can build up in artery walls.
- HDL cholesterol (“good” cholesterol) helps carry cholesterol away to the liver.
- Triglycerides are another type of fat that rises with excess calories, alcohol and sugar.
- Your cholesterol to HDL ratio is a useful summary of risk; lower is better.
High cholesterol usually has no symptoms, which is why a blood test matters. For a more detailed look at inherited and particle-based risk, choose our Cardiovascular Profile, which adds ApoB and lipoprotein(a) for the same price.
Who it’s for
- Adults who haven’t had their cholesterol checked recently
- A family history of heart disease or high cholesterol
- High blood pressure, diabetes or smoking
- Monitoring statins or diet changes
How to prepare
- Drink plenty of water beforehand; it makes the sample quicker and easier to take.
- You don’t usually need to fast. If you’ve been asked for a fasting test, don’t eat for 10–12 hours beforehand (water is fine).
Lipids (Cholesterol) Blood Test: your questions
Do I need to fast for a cholesterol test?
Usually not. Non-fasting tests are accurate for most purposes. If your doctor has asked for a fasting test, don’t eat for 10–12 hours beforehand.
What is a healthy cholesterol level?
As a general guide for healthy adults, total cholesterol of 5 mmol/L or below and LDL of 3 mmol/L or below. Targets are lower if you have heart disease or diabetes.
