The purpose of screening is early diagnosis and treatment. Screening tests are administered to people without current symptoms, but who may be at high risk for certain diseases or conditions.
The National Cholesterol Education Program recommends screening for lipid disorders at least once every 5 years starting at age 20. More frequent or earlier testing may be recommended if you have: A family history of elevated lipid levelsOther risk factors or conditions known to increase lipid levelsA complication that could have resulted from elevated lipid levels
Screening is recommended for children ages 9-11 years old and children 17-21 years old. For children of other ages, screening is only suggested if they have an increased risk factors such as: Have family history of heart disease or stroke in family members < 55 years old in males or < 65 years old in femalesHave parents with total cholesterol ≥ 240 mg/dL (6.2 mmol/L) or lipid disorderHave diabetes, high blood pressure, overweight, or obesitySmoke cigarettesHave moderate- or high-risk medical condition
Screening is not recommended in children under 2 years old.
Cholesterol levels are checked with a blood test. A blood sample is taken from a vein in your arm. You may need to fast for several hours before your blood is taken. The test measures levels of: Total cholesterolLDL (bad) cholesterolHDL (good) cholesterolTriglycerides
