High-sensitivity C-reactive protein (hs-CRP) is a powerful blood test that detects low-grade inflammation in the body—often before any visible symptoms arise. Unlike standard CRP tests, hs-CRP is designed to measure even the tiniest signs of chronic inflammation that may quietly damage your arteries over time. Elevated levels of hs-CRP are linked to a higher risk of heart attacks, strokes, and other cardiovascular events, even in people with normal cholesterol.This test acts like an early warning system for your heart, offering valuable insights into your long-term risk. It’s especially useful for those with risk factors like diabetes, high blood pressure, smoking, obesity, or a family history of heart disease. With just a simple blood draw, hs-CRP helps guide smarter lifestyle changes, preventive care, and peace of mind—because protecting your heart starts with knowing where you stand.
