High-sensitivity CRP (hs-CRP) measures chronic inflammation in your body. Your liver produces CRP in response to inflammation anywhere, making it a broad signal rather than a specific one. What makes hs-CRP especially useful is its strong link to cardiovascular risk: chronic low-grade inflammation is an independent risk factor for heart attack and stroke. Levels below 1 mg/L are low risk, 1-3 mg/L moderate risk, and above 3 mg/L high risk. Unlike standard CRP, which detects the large spikes seen in acute infections or injuries, hs-CRP picks up on low-grade inflammation that drives cardiovascular disease. The 2025 ACC/AHA guidelines recommend hs-CRP testing as part of cardiovascular risk assessment.
