CRP (C-Reactive Protein)
A marker of general inflammation in the body, used to help understand infection, injury, or chronic low-grade inflammation.
This is educational information, not a diagnosis. Only a doctor reviewing your full report and history can properly interpret your result.
What It Is
CRP is a protein produced by the liver that rises in response to inflammation anywhere in the body. It's a general marker — it signals that inflammation is present, not necessarily where or why.
Why It Matters
A high-sensitivity version of this test (hs-CRP) is sometimes used alongside other markers to understand chronic low-grade inflammation, which has links to metabolic and cardiovascular health over time.
Typical Reference Range
Standard CRP is often reported as roughly below 10 mg/L for the general test, while the more sensitive hs-CRP uses much lower bands, often below roughly 1, 1-3, and above 3 mg/L to describe relative risk categories.
What Can Affect Your Results
- Any recent infection, injury, or illness
- Chronic conditions involving inflammation
- Body weight
- Smoking
- Recent vaccination
When It's Typically Checked
CRP is checked when investigating suspected infection or inflammation, and hs-CRP is sometimes added to cardiovascular risk assessments.
