## Reference Range Comparison (nmol/L)

- **Longevity & Metabolic Optimal Range:** 0 – 30 nmol/L
- **Standard Lab Reference Interval ("Normal"):** 0 – 75 nmol/L
- **Why Standard Lab Ranges Mislead Patients:** Many labs report Lp(a) in mg/dL instead of molar units (nmol/L), which fails to account for kringle repeat isoform size variations. A reference range of <75 nmol/L is frequently used, yet progressive vascular risk begins escalating above 30 nmol/L and rises steeply past 100 nmol/L.
- **Pre-Draw Supplement Assay Interference Warning:** Isoform-sensitive commercial assays miscalculate total particle count by overestimating large isoforms and underestimating small high-risk isoforms. Ensure your laboratory utilizes an isoform-insensitive calibrated immunoassay (reported in nmol/L).
