Inflammation
What is CRP? Optimal Ranges & Function
Normal Range:0-3 mg/L
Optimal Range:0-1 mg/L
What is CRP?
C-Reactive Protein (CRP) is produced by your liver in response to inflammation. High-sensitivity CRP (hs-CRP) can detect low levels of chronic inflammation.
Why CRP Matters
Chronic low-grade inflammation is linked to heart disease, diabetes, and aging. CRP is a powerful predictor of cardiovascular events independent of cholesterol.
Symptoms of Low CRP
- Low CRP is ideal
- Indicates minimal inflammation
Symptoms of High CRP
- May have no symptoms
- Increased cardiovascular risk
- May indicate infection
- Associated with chronic disease

If Your CRP is High
When CRP is elevated, consider testing the following markers to get a more complete picture:
- Homocysteine — Additional cardiovascular risk marker
- IL-6 (Interleukin-6) — Measure inflammatory signaling
