High Blood Cholesterol: What You Need to Know, Part 2

What do your cholesterol numbers mean?

Everyone age 20 and older should have their cholesterol measured at least once every 5 years. It is best to have a blood test called a "lipoprotein profile" to find out your cholesterol numbers. This blood test is done after a 9 to 12 hour fast and gives information about your:

• Total cholesterol
• LDL (bad) cholesterol
• The main source of cholesterol buildup and blockage in the arteries
• HDL (good) cholesterol
• Helps keep cholesterol from building up in the arteries
• Triglycerides
• Another from of fat in your blood

If it is not possible to get a lipoprotein profile done, knowing your total cholesterol and HDL cholesterol can give you a general idea about your cholesterol levels. If your total cholesterol is 200 mg/dL or more or if your HDL is less than 40 mg/dL, you will need to have a lipoprotein profile done. See how your cholesterol numbers compare to the tables below.

HDL (good) cholesterol protects against heart disease, so for HDL, higher numbers are better. A level less than 40 mg/dL is low and is considered a major risk factor because it increases your risk for developing heart disease. HDL levels of 60 mg/dL or more help to lower your risk for heart disease.

Triglycerides can also raise heart disease risk. Levels that are borderline high (150 - 199 mg/dL) or high (200 mg/dL or more) may need treatment in some people.
