Understanding C-Reactive Protein (CRP): A Precise Marker of Inflammation

C-Reactive Protein — a key acute-phase reactant produced by the liver — serves as a sensitive biomarker for inflammation, infection, and tissue damage.When the body faces infection or injury, CRP levels rise rapidly, helping activate complement and enhance phagocytosis — the body’s way of clearing pathogens and damaged cells.

Why CRP Matters

Bacterial vs. viral infections: CRP increases sharply in bacterial infections but only slightly in viral ones — aiding in infection differentiation.

Cardiovascular disease: High-sensitivity CRP (hs-CRP) reflects vascular inflammation and predicts cardiovascular risk.

Chronic inflammation: CRP helps monitor autoimmune and inflammatory diseases, guiding treatment adjustments.

Post-surgery monitoring: Persistent CRP elevation may signal complications or infection.
