LDL Cholesterol

Also known as: LDL-C, Bad Cholesterol

Heart Blood
Patient Friendly Summary

Think of LDL as delivery trucks dropping cholesterol on artery walls. Fewer trucks, cleaner roads. Diet, exercise, and medicines when needed all reduce the traffic.

What this test means

LDL carries cholesterol into artery walls, where it can form plaques over years. It is the main treatment target in cholesterol management.

Why it is done

It is done as part of the lipid profile for heart-risk screening and to track response to lifestyle changes or medicines.

Understanding your value

If your value is high

High LDL may increase the risk of heart attacks and strokes over time, especially with smoking, diabetes, or high blood pressure.

If your value is low

Low LDL is generally favourable; very low values on treatment are usually intentional and monitored by your doctor.

About the normal range

Below 100 mg/dL is commonly optimal; people with existing heart disease or diabetes may be given lower personal targets.

When to consult a doctor

Review high LDL with your doctor — management depends on your total risk, not the number alone. Never start or stop statins on your own.
