The card shows an example result of 3.5 mg·L⁻¹, which is 2.71 SD above the mean.

What it measures

C-reactive protein is made by the liver when the body is inflamed. The high-sensitivity test measures it at very low levels, which picks up the slow, low-grade inflammation linked to heart and blood vessel disease.

Reference range

FieldValue
Abbreviationhs-CRP
GroupInflammation
Unitmg·L⁻¹
Healthy range0.2–3
Mean1.6
SD0.7
Direction↑ Bad — a raised value is the concern.

The mean is (low + high) / 2 and the SD is (high − low) / 4, so the healthy range covers Z from −2 to +2.

Reading the result

  • High — Points to ongoing low-grade inflammation and a higher cardiovascular risk. A short-term infection, injury, or hard exercise can also raise it.
  • Low — Not a concern. Low values mean little inflammation.

Notes

  • Values above 10 mg·L⁻¹ usually mean an acute infection or injury, not long-term risk. Repeat the test once you are well.
  • Read it alongside lipids and blood pressure, not on its own.
