hs-CRP measures systemic inflammation — a chronic, low-grade fire that drives cardiovascular disease, cognitive decline, and accelerated aging. Most people don't know their number.
The Stack Analyzer maps your goals and current data to the right measurement path, protocol, and stack — in order.
C-reactive protein (CRP) is produced by the liver in response to inflammation anywhere in the body. The high-sensitivity version (hs-CRP) can detect very low levels of chronic systemic inflammation — the kind that doesn't cause obvious symptoms but silently drives atherosclerosis, neurodegeneration, insulin resistance, and cellular aging.[1]
Acute CRP (from infection or injury) can reach 100+ mg/L. Chronic low-grade inflammation — the kind hs-CRP is designed to detect — operates in the 0.5–10 mg/L range, well below what triggers any clinical concern but meaningfully above optimal.
mg/L
Under 0.5 mg/L
Above 1.0 mg/L — warrants investigation
Above 3.0 mg/L — clinical conversation recommended
Don't test during illness or injury — wait 2–3 weeks. Recheck every 90 days if above 1.0 mg/L and intervening.
Reference ranges vary by lab, age, sex, medication status, and clinical context. Use these as discussion prompts with your clinician — not as diagnosis.
Always test hs-CRP when healthy — not during or shortly after an infection, injury, or dental procedure. Acute inflammation can temporarily raise hs-CRP to 50–100+ mg/L, completely obscuring your chronic baseline. Wait 2–3 weeks after any acute illness before testing.
The Stack Analyzer uses your measurements to build a personalized protocol, supplement stack, and 30-day plan.
