When there is inflammation in your body, the liver produces a substance called CRP or C-reactive protein. Elevated CRP levels in your blood is an indicator of inflammation. It can occur for a range of conditions from infections to cancer. It is our body’s mechanism of protecting tissues during the course of an infection [1].

Even when there is swelling in your arteries, your blood may contain high levels of CRP. If not diagnosed on time, this can cause a heart attack. Usually, the normal CRP levels in your body are low. A CRP test means a test that is done to check the levels of CRP in your blood. This CRP blood test is a non-specific test as your CRP levels may increase during any inflammatory condition. The C-reactive protein test has also been used as a type of COVID test.

Read on to understand more about this test and its importance.

Why should you do a CRP test?

A CRP test is used to detect certain health conditions that can cause inflammation in your body. A few of these conditions are as follows:

  • Infections occurring in the bone
  • Autoimmune disorders
  • Fungal infections
  • Bacterial infections
  • Inflammatory bowel disease

A CRP test helps in assessing cardiovascular diseases as it detects inflammation in your body. The reason for this inflammation is the increase in LDL levels. This causes plaque deposition in your arteries resulting in damage of arteries. To counteract this damage, your body produces certain proteins, one of which is CRP. With C-reactive protein, high counts indicate that you are suffering from heart ailments that may require further evaluation.

How is the test done?

You don’t need to fast before getting a CRP test done. Blood is extracted from your vein with the help of a small needle. You may experience a slight bruise or pain in the spot where the needle is inserted. This blood is collected in a small vial, which is later sent to the lab to assess CRP levels. The whole test can be completed in 5 minutes. In some cases, you may also experience dizziness. This gets better after a little while.

When should you be getting tested for CRP?

It is better to undergo a CRP test if you notice the following symptoms of either bacterial or viral infection [2]:

  • Rapid beating of the heart
  • Sudden chills
  • Fever
  • Vomiting
  • Rapid breathing
  • Nausea

In case you have contracted an infection, this test can also help you monitor your treatment. The CPR values fluctuate depending on the extent of inflammation. If your values decrease, it indicates that the treatment you are undergoing for inflammation is effective.

What is the CRP normal value?

CRP values are always measured in mg/L, where mg is milligrams of CRP in one liter of blood. The CRP normal range is always below 1mg/L. This also ascertains the fact that you are at low risk for acquiring cardiovascular diseases. If values exceed the CRP test normal range, it indicates that there is some inflammation that may require medical intervention. If the values lie between 1-2.9mg/L, you may be at intermediate risk for heart ailments. However, if your values shoot up beyond 3mg/L, there is a higher risk of cardiovascular diseases. In case the value increases more than 10mg/L, this is an indication of significant inflammation. In such cases, there are chances that you may have been infected with conditions like:

  • Tuberculosis
  • Cancer
  • Pneumonia
  • Autoimmune diseases
  • Bone infections

It is not always necessary that high CRP levels always indicate inflammation. These values also increase if you are taking birth control pills. Therefore, it is always better to speak to your doctor to understand your health conditions.
