Do you know there is a test for inflammation? The CRP test is used for inflammation. Inflammation is the response made by our body when there is tissue injury or infections by bacteria, fungi, viruses, and parasites. 

CRP Test: Full Form, Normal Range, Procedure, Cost

Let us know in detail the following points to clearly understand what the CRP test is and why we need it.

What Is a CRP Test? 

CRP test is a blood test used to check the presence of C-reactive protein in the serum that forms as a response to inflammation in the body.

C-reactive protein or CRP is a pentameric protein made by the liver in response to inflammation. Inflammation helps save our body from infections by microorganisms. Whenever there is injury or disturbance in our body inflammation happens. As a result of inflammation, there is fever, swelling, and pain.

Apart from the liver, CRP is also released from endothelial cells, adipose tissue, and muscle cells. 

Whenever there is inflammation, infection or trauma activates the inflammatory cells like neutrophils which in turn activates caspase-1 that converts Pro IL-1β to IL-1β. IL-1β stimulates the release of cytokine IL-6 that activates the CRP gene in hepatocytes. CRP gene is also activated by IL-1 and TNF- α. Once the CRP gene is activated, it starts forming C-reactive proteins that are nCRP. nCRP then forms a complex with the endoplasmic reticulum. When there is inflammation then nCRP gets detached from the complex and released into the bloodstream.

Now, you may be curious to know what happens after CRP is released into the bloodstream. Let me explain in detail because then you will understand the purpose of the CRP test.

After the release of CRP from hepatic cells, CRP decreases the expression of the eNOS (endothelial nitric oxide synthase) enzyme resulting in a decrease in nitric oxide production(NO) and an increase in ROS production. Also, increased levels of CRP in the serum increase the ET-1 receptors. All these combined result in endothelial dysfunction. Endothelial dysfunction results in various vascular diseases like coronary artery disease. Increased levels of CRP result in opsonization that results in uptake of ox LDL by macrophages. When the macrophages take up ox LDL it converts into foam cells. Foam cells result in atherosclerosis. 

After the macrophages get activated they trigger and activate the complement system that helps phagocytosis of microorganisms and dead cells by the macrophages.

What are the purpose and normal range of a CRP test? 

We have seen above that inflammation causes the levels of C-reactive protein to increase in the body. C-reactive proteins can also be increased due to 

  • Bacterial infections
  • Viral infections
  • Parasitic infections
  • Fungal infections
  • Cancers
  • Auto-immune disorders
  • Surgeries(2-3 days after surgeries)

The CRP test normal range in the serum is less than 10mg/L. But if the test result comes out to be more than or equal to 10mg/L then you need attention. 

We can see that the CRP test acts as a biomarker indicating that there is some sort of disturbance happening in our body that needs immediate medical treatment. For example- if a person has cancer then it can trigger inflammation that leads to swelling, pain, and fever. Inflammation causes CRP levels to increase. Hence, CRP tells the doctor the risk of inflammation and what steps need to be followed after the CRP test.

Uses of CRP test:

  • It is used to detect bacterial infections like sepsis.
  • It is used to detect a condition named Pelvic Inflammatory Disease (PID).
  • It is used to detect chronic inflammatory conditions like Inflammatory Bowel Diseases, autoimmune diseases, and arthritis.
  • It is used to detect infection after surgeries.

If high levels of CRP are not treated properly then it can lead to coronary artery disease and lead the risk of heart attack and stroke.

CRP Test Procedure - All You Should Know 

CRP test is a simple blood test that can be done at the hospital, diagnostic centre, or at home. 

  • A phlebotomist collects the blood in a tube from the vein with the help of a syringe.
  • A band will be wrapped in your arm for the collection of blood samples.
  • Then the blood will be collected with a syringe.
  • You may be asked to sit quietly after the sample is collected. This is done to check if there is any reaction at the site of injection or not. 
  • If you are fine then you may go back to your home and wait for the test results.

After the blood is collected then the sample is tested at the laboratory.

In the laboratory, the sample is mixed with latex reagent. After mixing them if agglutination of the latex particles occurs then there is CRP present significantly in the serum. 

Are there any risks associated with a CRP Test? 

There is no associated risk with a CRP test but you might feel dizzy. But you must look for the below complication:

  • Redness
  • Swelling
  • Pain
  • Excessive bleeding
