hs-CRP levels: what's normal, high and low
A sensitive marker of low-grade inflammation. Used for cardiovascular risk assessment.
Medically reviewed by Youmna DiStefano, MD · Last reviewed September 2026
The short answer
hs-CRP is measured with a standard blood draw; no fasting is needed. A typical reference range is 0.000 – 3.00 mg/L. At TestWell it's $34.99 all-in as Heart & Body Inflammation Test (hs-CRP), results in 2–4 business days, drawn at Quest or Labcorp. An out-of-range result is a prompt to look closer, not a diagnosis.

hs-CRP Reference Range
These are the typical adult reference ranges used by major US labs. Your report will include the specific range used by the lab that processed your sample.
| Population | Range |
|---|---|
| age 18+ | 0.000 – 3.00 mg/L |
Reference ranges are educational. Always interpret your result with the specific range printed on your lab report and discuss anything outside the range with a clinician.
What your hs-CRP result may mean
Above 3 mg/L suggests higher cardiovascular risk; above 10 mg/L often reflects acute infection or inflammation rather than chronic risk.
What a high hs-CRP means: causes, symptoms, next steps →Educational only — not a diagnosis. Many factors can influence a single result. Discuss anything that concerns you with a healthcare provider.
How do you get a hs-CRP test?
Order online, a licensed physician reviews the requisition, and you walk into a nearby lab for the draw. hs-CRP is available on its own or inside these panels — panels cost less per marker when you want the fuller picture.
| Option | Includes | Price |
|---|---|---|
| Heart & Body Inflammation Test (hs-CRP) | This marker only | $34.99 |
| Gout Panel | 3 tests | $62.99 |
| Autoimmune Screening Panel | 4 tests | $86.99 |
| Heart Health Panel | 5 tests | $99.99 |
| Post-COVID Recovery Panel | 7 tests | $99.99 |
Quest vs. Labcorp for hs-CRP: which lab should you pick?
Both are CLIA-certified national labs and the result is clinically equivalent, so pick whichever location is closer. Your report will print that lab's own reference range, which can differ slightly from the table above.
| Lab | Available | Price |
|---|---|---|
| Quest Diagnostics | Yes | $34.99 |
| Labcorp | Yes | $34.99 |
| BioReference (NY & NJ) | Yes | $37.99 |

How often should you retest hs-CRP?
For cardiovascular risk assessment, the AHA/CDC statement recommends averaging two hs-CRP measurements taken at least 2 weeks apart, and skipping the test during an infection, injury, or flare — any acute inflammation pushes CRP up for days and would hide your baseline. Retest once you've been well for at least two weeks.
General guidance from the sources listed below — your clinician may set a different schedule based on your history and results.

Frequently asked
Above 3 mg/L suggests higher cardiovascular risk; above 10 mg/L often reflects acute infection or inflammation rather than chronic risk. A single result above the reference range is a prompt to look closer with a clinician — often a repeat test and related markers — not a diagnosis on its own.
