C-Reactive Protein

Description

Overview of C-Reactive Protein (CRP) Test

The C-Reactive Protein (CRP) test is a blood test used to measure the level of ... CRP, a protein produced by the liver in response to inflammation. Elevated CRP levels indicate the presence of inflammation, which may be caused by infections, chronic diseases, or acute medical conditions.

Why is the CRP Test Done?

Doctors recommend a CRP test to:
✔ Detect infections and inflammatory diseases
✔ Monitor chronic conditions like rheumatoid arthritis, lupus, and inflammatory bowel disease (IBD)
✔ Assess heart disease risk with the high-sensitivity CRP (hs-CRP) test
✔ Check for post-surgical or injury-related inflammation

CRP Test Normal Range

• Less than 1 mg/L – Low inflammation
• 1-3 mg/L – Moderate inflammation
• More than 3 mg/L – High inflammation, indicating infection or chronic disease

Types of CRP Tests

1. Standard CRP Test – Measures general inflammation in the body.
2. High-Sensitivity CRP (hs-CRP) Test – Detects low levels of CRP to assess cardiovascular disease risk.

How is the Test Performed?

• A small blood sample is taken from a vein.
• No fasting is required for a regular CRP test.
• Results are usually available within a few hours to a day.
