What HDL Cholesterol Measures

HDL (high-density lipoprotein) acts like a cleanup crew in your bloodstream. It picks up excess cholesterol from tissues and artery walls and carries it back to the liver for disposal. Higher HDL levels are generally protective against heart disease.

Normal Ranges

Low (risk factor)< 40 mg/dL (men) / < 50 mg/dL (women)

Acceptable40–59 mg/dL

Optimal (protective)≥ 60 mg/dL

Reference ranges may vary slightly by lab. Always use the range provided on your specific test report.
