The CRP Test (C Reactive Protein Test) is a blood test that measures the level of C-Reactive Protein (CRP) in the body. CRP is a protein produced by the liver in response to inflammation.
This test helps detect the presence and severity of inflammation caused by infections, injuries, autoimmune conditions, and other inflammatory disorders. A quantitative CRP test provides an accurate measurement of CRP levels and helps doctors monitor disease activity and treatment response.
1.CRP (C Reactive Protein) Quantitative
Measures the exact amount of C-Reactive Protein in the blood, a protein made by the liver in response to inflammation.
Also known as: C-Reactive Protein Blood Test, CRP Quantitative Test, Inflammation Marker Test
The CRP Test is a commonly used laboratory test to assess inflammation in the body. When tissues are injured or the body responds to infections, the liver releases CRP into the bloodstream.
CRP levels can rise quickly during inflammation, making it a useful marker for detecting active inflammatory processes.
Doctors often recommend CRP testing along with other investigations such as Complete Blood Count (CBC), ESR, blood cultures, or autoimmune tests to understand the underlying cause of inflammation.
The CRP Test measures the amount of C-Reactive Protein present in the blood.
CRP is an acute-phase protein, meaning its levels increase when the body experiences inflammation due to:
The quantitative CRP test reports the exact CRP concentration in the blood, helping doctors evaluate inflammation severity and monitor changes over time.
Doctors may recommend a CRP Test to:
The test may be advised if you experience:
Benefits of the CRP Test:
A CRP Test may be recommended for:
A CRP Test requires a blood sample collected from a vein.
Before the test:
| Parameter | Normal range |
|---|---|
| CRP (C Reactive Protein) | Usually less than 5 mg/L in healthy individuals |
| General interpretation | |
| Normal / Low CRP | No significant inflammation detected |
| Mildly Elevated CRP | May indicate mild inflammation, infection, or other causes |
| Moderately Elevated CRP | May suggest active inflammation or infection |
| High CRP | May indicate significant inflammation requiring medical evaluation |
| Note | CRP levels should always be interpreted along with symptoms, medical history, and other laboratory findings. Reference ranges may vary between laboratories. |
Reference ranges can differ between labs. Your report shows the range used by the lab.
A CRP Test is a blood test that measures C-Reactive Protein levels to detect and monitor inflammation in the body.
No, fasting is usually not required for a CRP Test.
A high CRP level indicates increased inflammation in the body. It may occur due to infections, injuries, autoimmune conditions, or other inflammatory conditions.
Yes, CRP can help identify and monitor inflammation caused by infections, especially when interpreted with other clinical findings.

Both CRP and ESR are inflammation markers. CRP usually rises and falls faster during inflammation, while ESR changes more gradually and may remain elevated longer.
Yes. CRP levels may decrease when the underlying inflammation improves or after successful treatment.
No. CRP indicates inflammation but does not identify the exact cause. Doctors may recommend additional tests depending on symptoms and clinical findings.
