Doctor explains C-reactive protein (CRP) blood test!

In this video Doctor O'Donovan explains the CRP blood (lab) test including 1. What CRP is 2. Why the test is used 3. What the result of the test might mean.

What is being tested?

C-reactive protein (CRP) is an acute phase reactant, a protein made by the liver that is released into the blood within a few hours after tissue injury, the start of an infection or other inflammation. Increased concentrations in the blood can be found after a heart attack, in sepsis, and after a surgical procedure. It is often the first evidence of inflammation or an infection in the body, with rising concentrations frequently preceding pain, fever or other clinical indicators. The concentration of CRP in the blood can jump a thousand-fold in response to inflammation and can be valuable in monitoring disease activity.

The CRP blood test is not diagnostic but it provides information to the doctor as to whether inflammation is present. This information can be used by the doctor in conjunction with other factors, such as signs and symptoms, physical examination and other tests to determine if someone has an acute inflammatory condition, or if they are experiencing a flare-up of a chronic inflammatory disease. The doctor may then follow up with further testing and treatment.

How is the sample collected for testing?

A blood sample is obtained by inserting a needle into a vein in your arm.

Is any test preparation needed to ensure the quality of the sample?

No test preparation is needed.
