Description
The CRP test measures the level of C-reactive protein in your blood, a substance produced by the liver in response to inflammation. Elevated CRP levels can indicate that there is inflammation somewhere in the body.
Why the CRP Test Is Important
A CRP test helps diagnose and monitor inflammation associated with a variety of conditions, including:
- Infections
- Autoimmune disorders such as rheumatoid arthritis or lupus
- Inflammatory bowel disease
- Evaluating how well treatments for inflammation are working
By monitoring CRP levels, healthcare providers can assess disease activity and guide appropriate treatment plans.
