Overview
CRP is a protein produced by the liver in response to inflammation. Its level helps gauge the presence and severity of an inflammatory process.
Why it's done
It is ordered to monitor infection and inflammatory disease and to assess the response to treatment.
How to prepare
No special preparation is needed.
What to expect
A venous blood draw.
Understanding the results
A raised CRP indicates inflammation or infection but does not pinpoint the cause. A fall over time suggests treatment is working.
