LDL Small
Small dense LDL particles penetrate the arterial intima more easily, oxidize readily, and clear more slowly from blood than larger LDL. High concentrations raise cardiovascular risk even when total LDL cholesterol looks normal and commonly accompany high triglycerides, low HDL, and insulin resistance. Lifestyle changes and triglyceride-lowering therapy tend to reduce them.
Optimal range: who says what
No institution or named practitioner we track states an optimal target for LDL Small. How we verify ranges.
- General guidance, no named sourceLower is favorableSmall dense LDL carries the atherogenic association. Cutoffs are lab- and method-dependent
- Lab reference intervalVaries by lab methodologyWhat a lab report flags against. A lab interval is not an optimal target.

Why LDL Small matters
Small dense LDL particles are more atherogenic than larger particles, penetrating arterial walls more easily. High levels increase cardiovascular risk even when total LDL cholesterol is normal.
Which Providers Test LDL Small?
Blueprint is both the cheapest ($365/year) and the most comprehensive (100+ biomarkers) panel that includes LDL Small.
2 panels that include it, cheapest first
| Provider | Annual Cost | Total Biomarkers | $/Biomarker |
|---|---|---|---|
| $365 | 100+ | $3.65 | |
| $499 | 100+ | $4.99 |
$/Biomarker is annual cost divided by the panel's advertised biomarker count, not the price of this one test. We track 23 blood test providers (32 plans); 21 of those plans are itemized marker by marker. Compare all of them.
