What Is a C-Reactive Protein?
C-reactive protein (CRP) is a substance produced by the liver in response to inflammation. CRP is a biomarker of inflammation that is strongly associated with the risk of cardiovascular diseases, such as heart attacks and strokes.
A high level of CRP in the blood is a sign that there is inflammation in the body.
How Is C-Reactive Protein Measured?
A blood test can measure CRP levels. The normal range for CRP levels is 0.0-10 mg/L.

A high level of CRP in the blood is a sign that there is inflammation in the body. Inflammation is a normal response by the body to injury or infection.
