How to Test for CRP? C-Reactive Protein

Have you ever wondered why your doctor ordered a CRP test? What does it mean, and why is it important? In this blog post, we will explore the reasons behind ordering a CRP test and how it can provide valuable information about your health.

What is CRP?

C-Reactive Protein (CRP) is a protein made by the liver that rises when there is inflammation in the body. A CRP blood test measures CRP levels to help assess inflammatory conditions or disease risk.

Why is Inflammation Important?

Inflammation is a natural response of the immune system to protect the body from injury or infection. However, chronic inflammation can be a sign of an underlying health condition such as autoimmune diseases, infections, or cardiovascular diseases.

When is a CRP Test Ordered?

Doctors may order CRP testing if someone has signs/symptoms of:

  • Infection: High CRP indicates the body is fighting infection
  • Inflammation: To evaluate chronic inflammatory conditions
  • Heart Disease: Elevated CRP correlates with greater cardiovascular risks

A CRP test may be ordered for various reasons:

  1. Monitoring infections: When you have symptoms of an infection, such as fever, fatigue, or body aches, a CRP test can help determine the severity of the infection and guide the appropriate treatment.
  2. Assessing cardiovascular risk: High levels of CRP in the blood have been associated with an increased risk of heart disease. Your doctor may order a CRP test to assess your risk and develop a personalized prevention plan.
  3. Diagnosing autoimmune diseases: Inflammatory markers, including CRP, can be elevated in autoimmune diseases such as rheumatoid arthritis or lupus. A CRP test can help confirm the diagnosis and monitor disease activity.
  4. Evaluating chronic conditions: If you have a chronic condition like inflammatory bowel disease or chronic obstructive pulmonary disease (COPD), a CRP test can help monitor disease progression and response to treatment.

CRP stands for C-reactive protein, which is a substance produced by the liver in response to inflammation in the body. The CRP test measures the level of this protein in your blood and can help identify the presence and severity of inflammation.

How to Test for CRP?

A CRP test is a simple blood test that can be done in a laboratory or at your doctor's office. A healthcare professional will draw a small sample of blood from a vein in your arm using a needle. The sample will then be sent to a laboratory for analysis.

What Do the CRP Test Results Mean?

The results of a CRP test are typically reported as milligrams per liter (mg/L) of blood. Normal CRP levels are usually below 10 mg/L. Higher levels may indicate the presence of inflammation, but further testing may be needed to determine the underlying cause.

It's important to remember that a CRP test is just one piece of the puzzle. Your doctor will consider your symptoms, medical history, and other test results to make an accurate diagnosis and develop an appropriate treatment plan.

How to Prepare for Your CRP Blood Test?

No special preparation is needed for CRP testing. Stopping medications should be avoided. Our certified phlebotomists will draw a blood sample and send it for analysis at an accredited diagnostic lab.

Interpreting CRP Test Results

The normal CRP range is less than 10 mg/L. Levels between 10-20 mg/L suggest mild inflammation, and levels above 40 mg/L indicate serious infection or inflammation. Test results will be analysed by specialized doctors.


Next time your doctor orders a CRP test, you'll have a better understanding of why it's being done and how it can provide valuable insights into your health. Remember, knowledge is power, and being proactive about your health is the first step towards a healthier future!
