SampleA small tube of blood from a vein in your arm
Fasting?Usually not needed
ResultsSeveral days
Good to knowOne result rarely tells the whole story. Your provider looks at your results together with your symptoms, exam, and other tests.

What the test is

Many experts recommend checking it once in a lifetime. It barely changes with diet or exercise.

Why it's done

  • Family history of early heart disease
  • Heart disease without other clear risks
  • One-time risk check

Getting ready and what happens

  • No fasting is needed.

How the test is done

  • A health worker cleans the skin, puts a band around your arm, and draws blood from a vein with a small needle. It takes a few minutes.

What the results mean

ResultTypical range for adults
Higher riskAbout 50 mg/dL or higher (or about 125 nmol/L or higher)

Normal ranges vary from lab to lab and can differ by age, sex, and pregnancy. Your report lists your lab's own range next to each result. A result a little outside the range is often not a problem.

High

Your provider may lower your LDL more aggressively. Close relatives may want testing.

Questions to ask your provider

  • What do my results mean for me?
  • Do I need to repeat this test or have other tests?

Risks

A blood draw is very safe. You may have slight pain or a small bruise where the needle went in.
