Understanding CRP (C-Reactive Protein), Quantitative


What is CRP (C-Reactive Protein), Quantitative?

The CRP (C-Reactive Protein), Quantitative test is a simple blood test that measures the level of CRP, a protein produced by the liver, in the body. Usually, the CRP levels in the blood are low; however, these levels increase if you have inflammation. High CRP levels may indicate conditions like arthritis, infection, and injury.

C-reactive protein (CRP) is an early inflammation or infection marker. This protein is produced in the liver and is usually found at concentrations lower than 10 mg/L in the blood. However, CRP levels rise rapidly within the first 6 to 8 hours during infectious or inflammatory disease states. When the inflammation or tissue injury subsides, CRP levels also decrease, making it a valuable marker for monitoring disease progression. The CRP (C-Reactive Protein), Quantitative test measures the level of CRP; however, it does not show the exact location or the possible cause of the inflammation.

Your doctor may advise the CRP (C-Reactive Protein), Quantitative test if you experience symptoms suggestive of inflammation, such as fever, chills, redness, swelling, nausea, vomiting, rapid breathing, and/or rapid heart rate. If you have a previously diagnosed inflammatory condition, this test helps monitor how your treatment works and whether the issue is adequately managed. Moderately to severely elevated CRP levels may be a sign of possible infections, particularly after surgery or in other inflammatory conditions such as rheumatoid arthritis, lupus, or inflammatory bowel disease (IBD). High levels of CRP may also be due to genetics, exposure to environmental toxins, the use of birth control pills, and during pregnancy. 

No fasting is required for this test. You can eat and drink normally as per your routine. Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. Narrate your complete medical history to help them correlate your clinical and laboratory findings. The results will help the doctor determine your medical condition, make recommendations to manage your overall health, and formulate your treatment plan.

What is CRP (C-Reactive Protein), Quantitative used for?

The CRP (C-Reactive Protein), Quantitative test is done:

  • To check for bacterial or viral infections if you have symptoms such as fever, chills, redness, swelling, nausea, vomiting, rapid breathing, and/or rapid heart rate.
  • To detect and monitor the flare-ups of autoimmune diseases, like rheumatoid arthritis, lupus, inflammatory bowel disease (IBD), etc.
  • To assess the treatment efficacy of chronic inflammatory conditions.
  • To check for sepsis, a serious life-threatening medical emergency resulting from the body's extreme response to an infection.

What does CRP (C-Reactive Protein), Quantitative measure?

The CRP test measures the levels of C-reactive protein in your body. This test helps detect the presence of inflammation in the body. It is a non-specific test as it cannot diagnose a condition by itself or determine its exact location or cause. 

CRP is an acute phase reactant protein produced by the liver in response to an inflammation in the body. This inflammation may be due to tissue injury, infection, autoimmune diseases, or cancer. CRP levels are often increased before the onset of other symptoms of inflammation, such as pain, redness, fever, or swelling. These levels fall as the inflammation subsides.

Interpreting CRP (C-Reactive Protein), Quantitative results


Interpretations

Normal CRP level: Below 10 mg/L

Higher CRP levels than the normal range indicate the presence of an inflammation which may be caused by an infection, trauma, autoimmune diseases, cancers, etc.

The CRP Test is used to detect the presence of an inflammatory condition. Other tests and physical examinations are performed to diagnose a particular condition.

CRP levels are monitored at regular intervals to determine flare-ups in a chronic inflammatory condition and to monitor response to treatment.

Frequently Asked Questions about CRP (C-Reactive Protein), Quantitative

Q. Why is the CRP (C-Reactive Protein), Quantitative test done?

The CRP test is done to measure the level of CRP (C-Reactive Protein) hormone that serves as an early marker of inflammation and infection.
