High-Sensitivity C-Reactive Protein (hsCRP) is a protein produced by the liver in response to inflammation. Unlike standard CRP tests, the hsCRP test can detect even small elevations in CRP levels, making it useful for assessing cardiovascular risk.

Elevated hsCRP levels are indicative of inflammation, which is a key factor in the development of atherosclerosis. This inflammation can lead to the buildup of plaque in the arteries, increasing the risk of heart disease and stroke.

The hsCRP test is often used in conjunction with other risk factors to evaluate an individual's risk of cardiovascular disease. A level of 0–1 mg/L is generally considered low risk, while levels above 3 mg/L may indicate a high risk.

Frequently asked questions

What is a normal hsCRP level?
A normal hsCRP level is generally considered to be between 0–1 mg/L.
How can I lower my hsCRP levels?
Lifestyle changes such as a healthy diet, regular exercise, and quitting smoking can help lower hsCRP levels.
