CRP Level Reference Chart
Typical CRP interpretation ranges shown in both mg/L and mg/dL. Use this to check your converted result against common reporting bands.
| Interpretation | mg/L | mg/dL | General Meaning |
|---|---|---|---|
| Normal / Low Risk | < 3 | < 0.3 | No significant inflammation detected |
| Mild Elevation | 3 – 10 | 0.3 – 1.0 | Low-grade inflammation, minor infection |
| Moderate Elevation | 10 – 100 | 1.0 – 10.0 | Active infection or inflammatory condition |
| Marked Elevation | 100 – 500 | 10.0 – 50.0 | Significant bacterial infection or inflammation |
| Severe Elevation | > 500 | > 50.0 | Severe infection, sepsis, major trauma |
CRP Conversion FAQ
Everything you need to know about converting CRP results between mg/L and mg/dL.
To convert CRP from milligrams per litre (mg/L) to milligrams per decilitre (mg/dL), divide the mg/L value by 10. For example, a CRP result of 25 mg/L is equal to 2.5 mg/dL.
A normal CRP level is generally considered to be below 10 mg/L (1.0 mg/dL). Levels below 3 mg/L (0.3 mg/dL) are typically classed as low risk in cardiovascular screening, while levels above 10 mg/L usually indicate inflammation or infection.
Different laboratories and countries use different reporting conventions. Many use mg/L as the standard SI unit, while some, particularly in the US, report CRP in mg/dL. Both measure the same concentration of C-reactive protein, just scaled by a factor of 10.
A high CRP level indicates the presence of inflammation somewhere in the body, which can be caused by infection, injury, chronic disease, or autoimmune conditions. The exact cause cannot be determined from CRP alone and requires further clinical evaluation.
