When Should You Have a Cholesterol Test?

Some doctors and health organizations recommend that everyone older than 20 be checked for high cholesterol. How often you should be checked depends on whether you have other health problems and your overall chance of heart disease.

The U.S. Preventive Services Task Force (USPSTF) has guidelines for lipid disorder screening for adults.

Most experts agree that the following people should have their cholesterol checked:

• Anyone who has strong risk factors for heart disease
• People who have a family history of early coronary artery disease
• Men ages 35 to 65
• Women ages 45 to 65

An adult who has coronary artery disease should have a cholesterol test at least once a year.

An adult who is being treated for high cholesterol may need more frequent tests, depending on his or her cholesterol level and the type of treatment being used.

Most adults who have diabetes should be tested at least once a year.¹

For children, the USPSTF does not recommend for or against routine cholesterol screening, based on a review of the research.² But the American Heart Association and American Academy of Pediatrics (AAP) suggest that children and teens have their cholesterol levels tested if they have a family history of early coronary artery disease or have other risk factors.^{3, 4}

The AAP suggests that a child's risk of high cholesterol, based on a physical exam and family history, be checked at ages 2, 4, 6, 8, and 10 years, and then every year through age 21. The AAP also suggests that a cholesterol screening test be done between the ages of 18 and 21.⁵

Public cholesterol testing can be convenient and helpful. But most doctors will want to verify public test results. Because the doctor can evaluate risk factors and provide counseling, having your cholesterol level checked during a doctor visit is the preferred method.
