The purpose of screening is early diagnosis and treatment. Screening tests are usually administered to people without current symptoms, but who may be at high risk for certain diseases or conditions.
Blood tests—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:
LDL (bad) cholesterol
HDL (good) cholesterol
Cholesterol/HDL ratio (should be less than 5)
The National Cholesterol Education Program recommends screening for lipid disorders at least once every five years starting at age 20. More frequent or earlier testing may be recommended if you have a family history of elevated lipid levels or other risk factors or conditions known to increase lipid levels, or if your doctor finds a complication that could have resulted from elevated lipid levels.
