Test for C-Reactive Protein (CRP)

An c-reactive protein (CRP) assay is what?

A c-reactive protein (CRP) assay quantifies the concentration of c-reactive protein in a blood sample. The liver produces the protein known as CRP. Blood concentrations of C-reactive protein are typically modest. There is an increased release of CRP into the circulation by the liver in response to inflammation within the body. Elevated CRP levels may be a sign of a serious condition that causes inflammation.

The body employs inflammation as a physiological response to safeguard tissues and facilitate their recovery following an infection, injury, or ailment. Acute inflammation is characterised by its transient nature. In most cases, this form of inflammation is beneficial. A skin incision, for instance, may result in several days of redness, swelling, and pain. Such symptoms indicate inflammation. Additionally, inflammation can occur within the body.

Prolonged inflammation has the potential to cause harm to healthy tissues. The term for this condition is chronic inflammation. In addition to chronic infections and autoimmune disorders, other ailments are capable of inducing detrimental chronic inflammation. Additionally, chronic inflammation can develop when tissues are repeatedly irritated or damaged, as in the case of environmental toxins or smoking.

A CRP test can determine whether and to what extent an individual’s body is inflamed. However, the test is unable to determine the source of the inflammation or the specific anatomical site affected.

What is its function?

A CRP test may be used to detect or monitor inflammation in the following acute or chronic conditions:

Infections caused by viruses or bacteria
inflammatory bowel disease, intestinal disorders such as ulcerative colitis, and Crohn’s illness
Autoimmune disorders, including vasculitis, lupus, and rheumatoid arthritis
Lung conditions, including asthma
In the case of sepsis, your healthcare provider may use a CRP test to determine whether treatments for chronic inflammation are effective or to inform treatment decisions. Sepsis is the most severe response of the body to a blood-borne infection. A life-threatening medical emergency has ensued.


Why is a CRP test necessary?

If you have the following symptoms of a bacterial infection, you may require this test:

  • Anxiety or shivers
  • Elevated pulse rate
  • Rapid respiration
  • Experiencing nausea and vomiting
    If your healthcare provider suspects that you may have a chronic condition that induces inflammation, a CRP test may also be necessary. The symptoms are condition-specific.

In the event that an infection or chronic disease causing inflammation has already been identified, this test might be necessary to monitor the progress and efficacy of treatment. CRP levels fluctuate in response to the degree of inflammation within the body. Your decreasing CRP levels indicate that your anti-inflammatory treatment is effective or that you are recuperating naturally.


What occurs throughout a CRP test?

Using a small catheter, a medical professional will draw blood from a vein in your arm. A sample of blood will be collected into a test container or vial subsequent to the insertion of the needle. You might experience a mild pain when the needle is inserted or removed. Typically, this procedure requires no more than five minutes.


Do I require any additional preparation to take the exam?

Certain medications may influence your results. Therefore, inform your healthcare provider of any dietary supplements or medications you are currently using, such as ibuprofen, aspirin, or other non-steroidal anti-inflammatory drugs (NSAIDs). Before discontinuing any prescription medication, consult your healthcare provider.


What hazards are associated with the test?

The potential hazards associated with undergoing a blood test are minimal. Although minor discomfort or discoloration may occur at the site of needle insertion, the majority of symptoms resolve spontaneously.


What are the implications of the results?

The results of a CRP test indicate the degree of inflammation present in the body. The test results, however, are unable to identify the source of the inflammation. Your health care provider will consider your CRP results, symptoms, medical history, and the outcomes of additional tests in order to formulate a diagnosis.

Healthy individuals typically have extremely low levels of CRP in their blood. Any abnormal increases indicate the presence of inflammation within the body. However, laboratories calculate CRP levels differently and define “normal” CRP ranges differently; therefore, it is recommended to consult your provider regarding the significance of your results.


Should I be aware of anything else regarding a CRP test?

Sometimes, a CRP test and a high-sensitivity CRP test are confounded. Although they both measure CRP, their applications differ. hs-CRP tests detect minute increases in CRP concentrations. It is used to estimate cardiovascular disease risk.
