- What is the CRP Blood Test?
The C-reactive protein (CRP) blood test is a diagnostic tool used to detect inflammation in the body. CRP is a protein produced by the liver in response to inflammation, infection, or injury. The test measures the concentration of CRP in the blood and is useful for identifying both acute and chronic inflammatory conditions. - Why is CRP Important?
CRP levels rise when there is inflammation in the body, making this test valuable in detecting various conditions, such as infections, autoimmune disorders, and chronic diseases like rheumatoid arthritis. In addition, the high-sensitivity CRP (hs-CRP) test is often used to assess the risk of cardiovascular disease, as elevated CRP levels may indicate inflammation in the arteries. - Normal and Elevated CRP Levels:
- Normal: Less than 3 mg/L
- Elevated Levels: CRP levels higher than 3 mg/L suggest inflammation, with very high levels often exceeding 10 mg/L during acute infections or serious conditions like sepsis or inflammatory diseases.
- Low-Grade Inflammation (1-3 mg/L): May indicate chronic conditions, such as heart disease or diabetes.
- High-Grade Inflammation (>10 mg/L): May be caused by infections, autoimmune diseases, or trauma.
- What Do High CRP Levels Mean?
Elevated CRP levels suggest the presence of inflammation, but the test does not pinpoint the exact cause. Further testing is often required to determine the underlying condition. CRP levels are useful for monitoring the effectiveness of treatments for inflammatory diseases. - Why Regular Testing Matters:
Routine CRP testing helps monitor inflammatory conditions and guide treatment, especially in chronic diseases or cardiovascular risk assessment.
Recommended Tests:
- C-Reactive Protein (CRP) Test – Measures CRP levels to detect inflammation.
- Complete Blood Count (CBC) Test – Evaluates overall health and detects infections or anemia that may accompany inflammation.
