A high-sensitivity C-reactive protein (hs-CRP) test measures low levels of CRP in the blood with greater sensitivity than a standard CRP test. CRP is a marker of inflammation, and hs-CRP is often used to assess cardiovascular risk alongside other risk factors. Clinicians order it to add information about underlying inflammation when evaluating heart health, not as a stand-alone test for heart disease.

• High-sensitivity C-reactive protein (hs-CRP) A sensitive measure of low-grade inflammation that can be used to assess cardiovascular risk.

• People being assessed for cardiovascular risk.
• Individuals with risk factors such as high blood pressure or cholesterol concerns.
• Those with a family history of heart disease.
• People whose provider wants an inflammation marker.
• Anyone being monitored for chronic low-grade inflammation.

• No fasting is usually required for hs-CRP.
• Avoid testing during an active infection or illness.
• Avoid strenuous exercise right before the draw.
• Tell the provider about medications and recent illnesses.
• A standard blood draw is used for the sample.

Higher hs-CRP levels can be associated with more low-grade inflammation and may add to cardiovascular risk assessment, while lower levels are generally reassuring. However, CRP rises with infections, injuries, and other inflammatory conditions, so an elevated result is not specific to the heart. It is interpreted with other risk factors. Discuss your result with a healthcare provider.
