The high-sensitivity C-reactive protein (hs-CRP) test is a blood test that finds lower levels of C-reactive protein (CRP). This protein measures general levels of inflammation in your body. The hs-CRP can be used to find the risk for heart disease and stroke in people who don't already have heart disease.

The hs-CRP test is different than the standard CRP test. The standard test measures high levels of the protein to find different diseases that cause inflammation. The hs-CRP test measures low levels and focuses on the risk of heart disease and stroke.
