The C-Reactive Protein (CRP) test is a blood test that measures the level of CRP in your blood. CRP is a protein produced by the liver in response to inflammation. Inflammation is a normal immune system response to injury or illness. However, if you have chronic inflammation, your CRP levels may be elevated.
Elevated CRP levels can be a sign of conditions such as:
-Infection
-Cancer
-Autoimmune diseases
-Cardiovascular disease
If your doctor suspects you may have one of these conditions, they may order a CRP test. The results of this test can help your doctor make a diagnosis and develop a treatment plan.
