CRP (C-Reactive Protein)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 in healthy individuals. 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 not required for CRP blood test. You can eat and drink normally as per your routine. Inform your doctor about all the medications or supplements that you are taking as these may affect the test results.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.
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.
If you have conditions like arthritis, autoimmune diseases, or cardiovascular issues, discuss with your doctor how these might influence CRP test results.
Inform your healthcare provider about any medications or supplements you are taking, as some drugs (such as nonsteroidal anti-inflammatory drugs (NSAIDs), statins, or corticosteroids) may affect CRP levels.
Generally, fasting is not required for a standard CRP test. However, if you are undergoing a high-sensitivity CRP (hs-CRP) test to assess heart disease risk, your doctor may recommend fasting for 9–12 hours before the test.
