Description
A More Accurate Measure of “Bad Cholesterol” Risk
LDL cholesterol measures how much cholesterol is carried in the blood — not how many LDL particles are actually circulating.
The LDL Particle Number (LDL-P) Blood Test counts the total number of LDL particles, which is a stronger predictor of plaque formation and cardiovascular risk than LDL cholesterol alone.
More particles mean more opportunities for cholesterol to enter the artery wall — even when LDL cholesterol appears normal.
Why LDL-P Matters
You can have:
- Normal LDL cholesterol
- Elevated LDL particle number
- Increased cardiovascular risk
This mismatch is common in people with insulin resistance, metabolic syndrome, or elevated triglycerides.
LDL-P answers the key question:
How many LDL particles are damaging the arteries?
This Test Is Especially Useful If You Have:
- Family history of heart disease or stroke
- Normal LDL but ongoing cardiovascular concern
- Prediabetes or insulin resistance
- Metabolic syndrome
- Elevated triglycerides
- Low HDL cholesterol
- History of coronary calcium or plaque
What This Test Measures
- Total LDL particle number
- Reflects atherogenic particle burden
- Often measured using advanced lipoprotein analysis (such as NMR technology)
LDL-P has been shown to outperform LDL-C in predicting cardiovascular events in many populations.
Fasting
- Fasting is recommended for the most accurate results.
