High-sensitivity C-reactive protein (hs-CRP) is a non-specific marker of systemic inflammation, and chronically elevated values track with cardiovascular and metabolic risk. Because it is non-specific, a single high reading needs a repeat to separate a passing infection from a chronic pattern.

The biomarker

  • Name: hs-CRP (high-sensitivity C-reactive protein)
  • Units: mg/L
  • Standard reference range: < 3.0 (low cardio risk); 3–10 (moderate); > 10 (acute inflammation, repeat test)
  • Optimal range: < 1.0

How to read your result

Result (mg/L)Interpretation
< 1Low inflammation
1–3Average
3–10Elevated — chronic inflammation
≥ 10Acute process — investigate

What moves the needle

  • Diet. Add omega-3 and polyphenols and reduce processed foods.
  • Sleep. Prioritise 7–9 hours.
  • Stress. Add a daily recovery practice.
  • Acute readings. Repeat the test in about 2 weeks to confirm whether the elevation is chronic rather than a passing infection.

Why this test is worth asking for

  • It surfaces low-grade systemic inflammation that has no obvious symptoms but tracks with cardiovascular and metabolic risk.
  • Because it is non-specific, pairing it with the clinical picture — and a repeat test — separates chronic inflammation from a transient acute process.
  • It is inexpensive and widely available, making it a practical addition to a metabolic or cardiovascular work-up.
