## Reference Range Comparison (mg/dL)

- **Longevity & Metabolic Optimal Range:** 40 – 75 mg/dL
- **Standard Lab Reference Interval ("Normal"):** 40 – 130 mg/dL
- **Why Standard Lab Ranges Mislead Patients:** Commercial lab reference ranges consider ApoB up to 120-130 mg/dL normal simply because that represents the 50th percentile of sedentary Western populations. Atherosclerotic plaque accumulation essentially arrests when ApoB is maintained below 60 to 70 mg/dL, as seen in genetic PCSK9 loss-of-function variants.
- **Pre-Draw Supplement Assay Interference Warning:** Severe hypertriglyceridemia (>800 mg/dL) causes turbidity that may interfere with immunoturbidimetric and nephelometric light scatter assays. Fasting 10 to 12 hours is recommended to minimize chylomicron-associated ApoB-48 cross-reactivity.
