A lipid profile is a blood test that measures the fats in your blood. It is one of the most common checks for heart health, and it is often advised as part of a yearly health check.

What the report shows

  • Total cholesterol: the overall amount of cholesterol in your blood.
  • HDL cholesterol: often called the “good” cholesterol, because it helps carry cholesterol away from your arteries. Higher is generally better.
  • LDL cholesterol: often called the “bad” cholesterol, because too much of it can build up in the walls of blood vessels.
  • Triglycerides: another type of fat. High levels are linked to diet, weight, alcohol and some medical conditions.
  • VLDL cholesterol: a form of cholesterol that carries triglycerides.

Do I need to fast?

Many labs ask for 9 to 12 hours of fasting, with water allowed, because food can raise triglycerides. Follow the instructions given when you book.

Reading your numbers

Your report lists a reference range next to each value. A number outside the range does not always mean there is a problem, because age, sex, family history and other health conditions all matter. Your doctor will look at the full picture and tell you if you need changes in lifestyle, repeat tests or treatment.

Who should test, and how often?

Adults are usually advised to check their lipids regularly. People with diabetes, high blood pressure, a family history of heart disease or who smoke may need to test more often. Ask your doctor what suits you.
