The Cytokine Response
C-Reactive Protein is an acute-phase reactant produced by the liver. The high-sensitivity (hs) version detects low-grade vascular inflammation that traditional CRP tests miss, acting as a proxy for your "biological fire."
1
Vascular Health
Consistent levels above 2.0 mg/L are associated with increased cardiovascular risk even with normal cholesterol.
2
Exercise Spike
Intense training can temporarily spike CRP; test at least 48 hours after your last hard workout.
Optimal hs-CRP Benchmarks
Functional Range (Longevity Focused) < 0.5 mg/L
Standard Lab Range < 1.0 mg/L (Low Risk)
Common Questions
Is hs-CRP the same as regular CRP?
No. hs-CRP measures much smaller increments (0.1–10 mg/L) to detect chronic inflammation, whereas regular CRP is for acute infection.
