High-sensitivity CRP (hsCRP) measures very low levels of C-reactive protein, a marker of inflammation.
Used to assess cardiovascular risk: below 1 mg/L is low risk, 1–3 mg/L average, and above 3 mg/L higher risk. It adds to cholesterol results in predicting heart attack and stroke.
Adults over 30, people with high BP, diabetes, obesity, smoking or a family history of heart disease; chest pain or breathlessness (seek urgent care).
No fasting needed.
