A C-reactive protein test measures the level of C-reactive protein (CRP) in the blood. This protein is made by your liver and is sent into the bloodstream in response to an inflammatory process.
Inflammation is a process by which the body protects the tissues if they have been injured or have an infection. It can cause redness, pain, and swelling in the affected area. Autoimmune disorders or chronic diseases can also cause inflammation.
Typically, an individual should have low levels of C-reactive protein in the blood, while high levels may signify a severe infection or other disorder.
CRP levels increase and decrease depending on how much inflammation the body has. If the CRP levels go down, it's a sign that the treatment for inflammation is working.
Physicians typically order a C-reactive protein test to help diagnose or rule out certain conditions, including:
A practitioner may also request the CRP test to:
A CRP test alone can't determine where the inflammation is in the body. If a CRP is high, physicians will generally order additional tests to find the root cause of inflammation.
This is a single-marker test measuring C-reactive protein (CRP). It is used to test for inflammation, infections, and neoplastic diseases.
