C-Reactive Protein (CRP)

The CRP Test measures C-reactive protein, a substance that rises in the blood when there is inflammation. High CRP levels can suggest infection, injury, or chronic inflammatory conditions, while lower levels are linked with healthier immune and heart function.

Early Detection

C-Reactive Protein (CRP)

Experiencing fever, joint discomfort, or suspected infection and want to assess your body's inflammatory response and immune system activity?

Overview

Think of the CRP test as your body's inflammation detector – it measures a special protein that acts like an internal alarm system, alerting you when something's not quite right. When your body encounters an infection, injury, or other threat, your liver quickly produces C-reactive protein (CRP) as part of your immune system's response, much like how a smoke detector sounds when it senses danger.

This simple blood test reveals whether inflammation is present in your body and how active it might be. Elevated CRP levels can indicate anything from a common infection to chronic conditions like arthritis or autoimmune diseases, while normal levels suggest your body isn't currently fighting any significant inflammatory battles. Whether you're experiencing unexplained symptoms like persistent fatigue or joint pain, monitoring a known inflammatory condition, or recovering from surgery, the CRP test gives you and your healthcare provider valuable insight into what's happening beneath the surface, helping guide treatment decisions and track your progress toward better health.

Frequently Asked Questions

  • CRP is a protein produced by the liver during inflammation, serving as a general marker for infection, inflammatory diseases, or tissue damage.
