Standard reference ranges in conventional medicine are designed to catch clinical disease states after tissue damage has occurred. However, longevity science operates on a different standard: functional optimization.
Your calendar age reflects chronological time, but your blood chemistry reveals your biological age—the functional speed at which your vascular system, organs, and mitochondria are deteriorating.
By tracking specific blood biomarkers, you can detect subtle metabolic shifts, micro-inflammation, and cellular stress long before they manifest as chronic disease. Below is the definitive list of the top 10 blood biomarkers to track, along with optimal longevity targets to measure real progress.
1. Apolipoprotein B (ApoB)
While standard lipid panels report Low-Density Lipoprotein Cholesterol (LDL-C), ApoB measures the exact count of all atherogenic particles (including LDL, VLDL, and IDL). Every atherogenic particle carries exactly one ApoB molecule, making it a direct indicator of vascular oxidative burden and arterial plaque formation.
-
Standard Target: $< 100 \text{ mg/dL}$
-
Longevity Optimal Target: $< 60\text{–}70 \text{ mg/dL}$
2. High-Sensitivity C-Reactive Protein (hs-CRP)
Chronic, low-grade systemic inflammation—often called inflammaging—accelerates cellular senescence and damages delicate DNA methylation patterns. hs-CRP measures liver protein synthesis triggered by circulating inflammatory cytokines (such as IL-6).
-
Standard Target: $< 3.0 \text{ mg/L}$
-
Longevity Optimal Target: $< 0.5 \text{ mg/L}$
3. Fasting Insulin
Blood glucose can remain deceptively normal for decades because the pancreas overproduces insulin to compensate for tissue resistance. Elevated Fasting Insulin is an early indicator of metabolic dysregulation, mitochondrial decay, and accelerated cellular aging.
-
Standard Target: $< 25 \text{ uIU/mL}$
-
Longevity Optimal Target: $2.0\text{–}5.0 \text{ uIU/mL}$
4. Hemoglobin A1c (HbA1c)
HbA1c measures the percentage of red blood cells coated with glucose, reflecting average glycemic exposure over the past 90 days. High circulating glucose leads to Advanced Glycation End-products (AGEs), which stiffen arteries and cross-link collagen fibers.
-
Standard Target: $< 5.7\%$
-
Longevity Optimal Target: $4.8\text{–}5.2\%$
5. Homocysteine
Homocysteine is an amino acid byproduct of methionine metabolism. Elevated levels signal impaired cellular methylation—a key mechanism evaluated by modern epigenetic clocks—and increase the risk of vascular and neurodegenerative damage.
-
Standard Target: $< 15 \text{ umol/L}$
-
Longevity Optimal Target: $6.0\text{–}8.0 \text{ umol/L}$
6. Serum Ferritin
Iron is essential for oxygen transport, but excess iron storage generates toxic hydroxyl free radicals via the Fenton reaction. High Ferritin drives mitochondrial oxidative stress and accelerates cellular wear.
-
Standard Target: $30\text{–}400 \text{ ng/mL}$
-
Longevity Optimal Target: $40\text{–}100 \text{ ng/mL}$ (Men & Postmenopausal Women)
7. Fasting Triglyceride-to-HDL Ratio
This simple calculation acts as a practical marker for insulin sensitivity and atherogenic small dense LDL particles. Higher ratios strongly correlate with metabolic syndrome and systemic microvascular stress.
-
Standard Target: $< 3.0$
-
Longevity Optimal Target: $< 1.0$ (Triglycerides divided by HDL)
8. Alanine Aminotransferase (ALT) & Gamma-Glutamyl Transferase (GGT)
While ALT measures general liver enzyme release, elevated GGT specifically indicates visceral fat deposition, reduced glutathione storage, and intracellular oxidative stress.
-
Standard Target: ALT $< 45 \text{ U/L}$; GGT $< 60 \text{ U/L}$
-
Longevity Optimal Target: ALT $< 20 \text{ U/L}$; GGT $< 15\text{–}20 \text{ U/L}$
9. Estimated Glomerular Filtration Rate (eGFR) & Cystatin C
Kidney function naturally declines with age, but tracking Cystatin C alongside eGFR provides a precise readout of microvascular health and filtration capacity unaffected by muscle mass variations.
-
Standard Target: eGFR $> 60 \text{ mL/min/1.73m}^2$
-
Longevity Optimal Target: eGFR $> 90 \text{ mL/min/1.73m}^2$; Cystatin C $< 0.8 \text{ mg/L}$
10. Dehydroepiandrosterone Sulfate (DHEA-S)
DHEA-S is an adrenal steroid hormone precursor that peaks in early adulthood and declines steadily with age. It reflects adrenal resilience, immune system modulation, and overall endocrine vigor.
-
Standard Target: Varies widely by age
-
Longevity Optimal Target: Upper 25th percentile for healthy 25-to-30-year-olds
