C-Reactive Protein Screening

Scientists discovered C-reactive Protein (CRP) in the 1930s while exploring human inflammatory response. The role CRP plays in heart disease has only recently been discovered. It’s now believed that high CRP levels are associated with cardiovascular disease, stroke, coronary heart disease, peripheral arterial disease, and type 2 diabetes.

CRP is part of the immune system and is released into the blood when the body responds to injury or infection. Within 24 to 48 hours of an infection or trauma, CRP levels can increase 1000-fold.

The high-sensitivity C-reactive Protein (hs-CRP) screening measures CRP levels in the blood. In 2003, the American Heart Association and the Centers for Disease Control and Prevention announced that CRP >3 mg/L indicates a high risk for cardiovascular disease, even if cholesterol levels are low.

Screening for C-reactive Protein

  • A simple finger-stick screening that measures CRP levels in your blood, this test can help determine heart disease and stroke risk levels.

Who should have a C-reactive Protein screening?

  • Anyone who has risk factors for heart disease, peripheral arterial disease, diabetes or stroke

How often should I get a C-reactive Protein screening?

  • It's a personal decision based on risk factors, but many people have a screening annually.

*Recommended guidelines only. Consult with your physician.

How do I prepare for a C-reactive Protein screening?

  • There is nothing you need to do in advance

Warning signs

  • There are no warning signs for C-reactive Protein. This is a test that evaluates risk for coronary artery disease.
  • Coronary artery disease is a condition in which the arteries of your heart are narrowed, which can eventually lead to a heart attack.
