CRP Test Meaning And When To Do It

If you’ve recently had blood work or your doctor suspects an infection or inflammation, they may have recommended a CRP test. But what is it? Why is it important? And when exactly should you get it done?

Let’s simplify the medical jargon and walk you through the CRP test meaning and when to do it, especially in the Indian healthcare context.

What Is a CRP Test?

CRP stands for C-reactive protein. It is a substance produced by your liver in response to inflammation in the body.

The CRP test is a blood test that measures the amount of C-reactive protein in your blood. High levels of CRP usually mean there’s inflammation in your body, which could be due to an infection, injury, or a chronic disease like arthritis.

High CRP = Inflammation Alert

This test doesn’t tell you what’s causing the inflammation—it simply tells you that something is wrong, and further testing might be needed.

What Does the CRP Test Detect?

While CRP is a general marker, it is helpful in detecting:

• Bacterial or viral infections
   

• Autoimmune disorders like rheumatoid arthritis or lupus
   

• Inflammatory bowel diseases
   

• COVID-19 severity
   

• Heart disease risk (especially with high-sensitivity CRP or hs-CRP)
   

When Should You Do a CRP Test?

You should get a CRP test done when:

1. You have fever or chills that won’t go away
    

2. You’re showing signs of infection like cough, swelling, or pain
    

3. Your doctor is monitoring an autoimmune disease
    

4. You’re recovering from surgery or injury
    

5. Your doctor is checking inflammation due to chronic disease
    

6. You are showing COVID-like symptoms (to assess severity)
    

Normal CRP Levels:

Note: For heart disease risk, a high-sensitivity CRP (hs-CRP) test is used.

Is Fasting Required for the CRP Test?

No, fasting is not required. You can take the CRP test at any time of day, unless it is being done with other tests that require fasting (like blood sugar or cholesterol).
