What It Measures
The concentration of small, dense LDL particles in the blood, typically measured via NMR spectroscopy.
Small dense LDL particles are more atherogenic than large buoyant LDL because they penetrate the arterial wall more easily and are more susceptible to oxidation.
Current Value
326nmol/L
Reference Range: 0 – 117 nmol/L(standard)
Optimal Range: 0 – 80 nmol/L(Function Health, LabCorp, Quest Diagnostics)
0.0 (0.0%) from previous test
0 nmol/LOptimal: 0–80117 nmol/L
What High Means
Elevated small dense LDL increases cardiovascular risk even when total LDL-C is normal. Driven by insulin resistance, high triglycerides, and metabolic syndrome.
Possible Symptoms
No direct symptoms
What Low Means
Low small dense LDL is protective, indicating a favorable LDL particle size pattern.
Possible Symptoms
None
Risk Factors
Atherosclerosis, heart disease, metabolic syndrome
