Understanding C-Reactive Protein (CRP)

Annular pentameric protein found in blood plasma whose circulating concentrations rise in response to inflammation.

C-reactive protein (CRP) is a protein produced by the liver in response to inflammation in the body. It is often used as a marker of inflammation and can help detect, monitor, and evaluate a range of conditions.

The Role of CRP in the Body

CRP is part of the body's immune response. When there is inflammation in the body, the liver responds by producing more CRP. This protein then binds to the surface of dead or dying cells and some types of bacteria in order to activate the immune system.

CRP as a Marker of Inflammation

Because CRP levels increase when there's inflammation in the body, it is often used as a marker of inflammation or infection. Doctors can measure CRP levels through a simple blood test. This test can help detect or monitor conditions that cause inflammation, such as infections, autoimmune diseases, and cardiovascular disease.

Conditions Associated with Elevated CRP Levels

Elevated levels of CRP in the blood can indicate a variety of conditions. These include:

• Infections, such as pneumonia or a urinary tract infection
• Autoimmune diseases, such as lupus or rheumatoid arthritis
• Chronic diseases, such as heart disease and diabetes
• Certain cancers, such as lymphoma and colon cancer

It's important to note that while a high CRP level can indicate these conditions, it is not specific. This means that a high CRP level can't confirm a specific diagnosis, but it can suggest that there's inflammation or a disease causing inflammation in the body.

In conclusion, understanding CRP and its role in the body can provide valuable insights into your health. It can help you and your healthcare provider identify inflammation in the body and monitor the progress of diseases that cause inflammation.
