C Reactive Protein (CRP)

The C-Reactive Protein (CRP) test is a vital diagnostic tool used to identify inflammation within the body. Since CRP is a protein produced by the liver that spikes in response to injury or infection, this test is incredibly helpful for detecting hidden issues—ranging from acute bacterial infections and physical trauma to chronic inflammatory conditions like rheumatoid arthritis or lupus. By providing a clear snapshot of the inflammatory status, the test helps your doctor determine the severity of a flare-up, monitor how well you are responding to a specific treatment, or assess the risk of future cardiovascular events. Essentially, it acts as an early warning system that something in your internal environment requires attention.
