High-Sensitivity C-Reactive Protein

A sensitive marker of low-grade, body-wide inflammation linked to cardiovascular and metabolic risk. Highly variable — a single high value is often just a recent cold or workout.

This page is general wellness education, not medical advice. Your own lab’s reference range and your clinician’s interpretation always take precedence.

Typical reference range

GroupGeneral range
Adults<1 lower CV risk; 1–3 average; >3 higher

Optimal-band note: <1 mg/L is associated with lower cardiovascular risk; transient elevations occur with any infection/injury.

Units: mg/L. Ranges vary by lab and assay — read yours against the range printed on your own report.

What high High-Sensitivity C-Reactive Protein can mean

  • Infection/illness
  • Obesity
  • Smoking
  • Recent intense exercise/injury
  • Chronic inflammation

What low High-Sensitivity C-Reactive Protein can mean

  • Low inflammatory burden (good)
