An LDL Cholesterol test directly measures low-density lipoprotein cholesterol, often called “bad” cholesterol. High LDL contributes to plaque buildup in arteries, increasing heart disease and stroke risk.
What This Test Measures
LDL Cholesterol (Direct Measurement):
This test directly measures LDL rather than calculating it from other lipid values. Direct measurement is more accurate, especially when triglycerides are elevated or after eating.
Understanding Your Results
• Optimal: Less than 100 mg/dL
• Near Optimal: 100-129 mg/dL
• Borderline High: 130-159 mg/dL
• High: 160-189 mg/dL
• Very High: 190 mg/dL and above
For those with heart disease or diabetes, target is often below 70 mg/dL.
Why LDL Matters
LDL carries cholesterol to arteries where it can accumulate, forming plaques that narrow arteries (atherosclerosis). This leads to:
• Heart attack
• Stroke
• Peripheral artery disease
Lowering LDL significantly reduces cardiovascular risk.
Who Should Consider This Test
• Cardiovascular risk assessment
• Monitoring cholesterol-lowering medications (statins)
• Family history of heart disease or high cholesterol
• Diabetes or metabolic syndrome
• Follow-up to abnormal lipid panel
