About this test
What is CRP?
C‑Reactive Protein (CRP) is a protein produced by the liver in response to inflammation. The test measures the amount of CRP in the blood.
Key Parameter
| Parameter | What it shows |
|---|---|
| CRP level (mg/L) | Degree of inflammation in the body |
Why it is done
- Routine check‑up for patients with chronic inflammatory conditions.
- Evaluation of symptoms such as fever, pain, or unexplained fatigue.
- Monitoring disease activity in conditions like rheumatoid arthritis or inflammatory bowel disease.
Early Detection
CRP can help identify signs of inflammatory or infectious conditions, but it does not diagnose a disease on its own. A doctor interprets the result together with symptoms, history, and other tests.
What an abnormal result may mean
- High CRP: Indicates active inflammation or infection; could be due to bacterial infection, autoimmune flare, or other inflammatory processes. Many factors—hydration, recent exercise, medications—can influence the level.
- Low CRP: Generally indicates no significant inflammation, but very low levels can also occur in certain chronic conditions.
Who might get this test
- Individuals with persistent pain, swelling, or redness.
- Patients with known inflammatory or autoimmune diseases.
- People experiencing unexplained fever or infection.
Quick Summary
CRP is a blood test that measures inflammation. It helps doctors assess disease activity and monitor treatment, but it is not a standalone diagnostic tool.
Used for detecting / monitoring
Before your test
Preparation
- Fasting: No fasting required for CRP.
- If combined with fasting tests: Follow the longest fasting period required among all tests.
- Procedure: A healthcare professional will draw a small amount of blood from a vein in your arm using a needle. The process takes about 5 minutes.
- Discomfort: You may feel a brief pinch when the needle is inserted; the sample is usually painless afterward.

- Note: Confirm any specific preparation instructions with your doctor or the lab. This information is general educational guidance and not a substitute for professional medical advice.
