This is the next generation of proactive heart health. The hs-CRP test is not a standard inflammation test; it is a highly sensitive tool that detects low-grade, chronic inflammation inside your blood vessels—the 'hidden' inflammation that leads to plaque and heart attacks. This is a critical, independent risk marker. You can have normal cholesterol and still be at high risk if this level is elevated. This simple blood test is an essential, modern addition to any lipid profile, giving you the true picture of your cardiovascular risk.
