How reports print it
What it shows
The same C-reactive protein measured by a highly sensitive method: it tells apart levels around 1 mg/L and below. It is used to assess cardiovascular risk in people without acute inflammation.
Units and conversion
Base unit: mg/L.
- 1 mg/dL = 10 mg/L · 1 mg/L = 0.1 mg/dL
Typical ranges
Your laboratory’s range comes first — it is printed on the report next to the result. Below is one laboratory’s adult range with its method: a reference, not a rule.
| Who | Range, mg/L |
|---|---|
| Adults | 0–1 |
Range source: Лаборатория Хеликс — С-реактивный белок, высокочувствительный
Guideline thresholds
They apply on top of the range, for adults outside pregnancy. They are a reason to talk to a doctor, not a conclusion.
- CRP above 10 mg/L is, per Helix, a reason for further tests.

Good to know
Helix gives a range of 0–1 mg/L. For cardiovascular risk: below 1 mg/L low, 1–3 average, above 3 high (Helix, AHA/CDC 2003). If hs-CRP is above 10 mg/L, the test is repeated and inflammation is looked for. The baseline level is assessed no earlier than 2 weeks after an acute illness.
Why it can be higher
Common reasons discussed with a doctor. This is not a diagnosis.
- A recent infection or a flare of chronic inflammation
- Injuries and surgery
- Smoking
- High blood pressure, diabetes, high LDL or triglycerides
Why it can be lower
- A low hs-CRP is the usual picture without inflammation
- Some medicines, such as statins
What to ask a doctor
- Is it worth repeating the test 2 weeks after an illness?
- How does hs-CRP fit with my lipid panel and overall risk?
Whom to see
A GP or internist; then a cardiologist.
