Description:C-reactive protein (CRP) is a protein made in the liver. The level of CRP increases when inflammation is present in the body. A high-sensitivity C-reactive protein (hs-CRP) test is more sensitive than a standard C-reactive protein test. That means the high-sensitivity test can find smaller increases in C-reactive protein than a standard test can.

The hs-CRP test can help show the risk of getting coronary artery disease. In coronary artery disease, the arteries of the heart narrow. Narrowed arteries can lead to a heart attack.

A high level of hs-CRP in the blood has been linked to an increased risk of heart attacks. Also, people who have had a heart attack are more likely to have another heart attack if they have a high hs-CRP level. But their risk goes down when their hs-CRP level is in the typical range.
