A lipid profile is a blood test that measures the fats in your blood, mainly cholesterol and triglycerides. It is used to assess your risk of heart and blood vessel disease.
What does the test measure?
The test measures total cholesterol, LDL cholesterol, HDL cholesterol, and triglycerides. LDL is often called the bad cholesterol because high levels can build up in artery walls. HDL is often called the good cholesterol because it helps remove cholesterol from the blood. Triglycerides are another type of fat in the blood.
How to prepare
A lipid profile usually requires fasting for 9 to 12 hours beforehand. You can drink water, but no food or other drinks. Confirm with the laboratory whether fasting is needed for your test. The sample is a blood draw, and results are typically ready the same day.
What the result can mean
High LDL or total cholesterol, or high triglycerides, can increase the risk of heart disease over time. Higher HDL is generally associated with lower risk. These numbers are read together, not in isolation, and are interpreted alongside your age, blood pressure, smoking history, and other factors. Your doctor will explain your overall risk and what, if anything, needs to change.
When is it ordered?
A lipid profile is part of routine health checks, especially for adults, and is ordered more often for people with a family history of heart disease, high blood pressure, diabetes, or who smoke. It is also used to monitor how well diet, exercise, or medication is working.
