What LDL Cholesterol measures
LDL (low-density lipoprotein) carries cholesterol from the liver to cells throughout your body. When there's more LDL than cells need, it can deposit in artery walls, forming plaques that narrow arteries and increase heart attack and stroke risk over time.
Normal ranges
Reference ranges may vary slightly by lab. Always use the range provided on your specific test report.
What affects your ldl cholesterol level
- Diet high in saturated and trans fats

When to see your doctor
LDL consistently above 160 mg/dL usually warrants discussion with your doctor, especially if you have other risk factors like family history, smoking, or high blood pressure. Lifestyle changes typically reduce LDL by 10–30% before medication is considered.
