Understanding your CRP results
A C-reactive protein test measures a specific protein produced by the liver that increases in response to inflammation in the body. Healthcare providers often request this simple blood test to evaluate overall immune activity or to follow the course of a healing process.
What is the normal CRP range?
- India
- No India-specific national reference interval is published for this parameter; your lab's printed range is the most reliable comparison.
- International
- <10 mg/L generally considered within the normal range for conventional CRP assays; values >10 mg/L suggest significant inflammation or infection
Ranges vary by lab, method and equipment — the range printed on your own report is the one that applies to your result.

What does a high CRP result mean?
A higher CRP means the body is mounting an inflammatory response. This can come from infection, autoimmune activity, injury, or other causes. It is worth discussing with your doctor.
What does a low CRP result mean?
A low or undetectable CRP suggests no major body-wide inflammation at the time of the test.
What affects your CRP result?
Recent viral or bacterial infections, physical trauma, intense exercise, and ongoing autoimmune conditions can all cause these levels to rise and fluctuate.
- Bacterial infections usually raise CRP more than viral ones
- CRP rises within about 6 to 8 hours and peaks around a day or two
- Extra body weight and metabolic syndrome can nudge the baseline up
- Medicines that lower the immune response can blunt the CRP rise
- CRP is broad, so read it with your symptoms and other tests
Frequently asked questions
- What does an elevated result generally indicate?
- A higher result typically suggests the presence of inflammation somewhere in the body, though the test itself does not pinpoint the exact location or specific cause.
- Is fasting required before having the blood drawn?
- Fasting is usually not required for this test alone, though a doctor might advise it if other routine blood tests are being drawn during the same visit.
- How should an individual review their report?
- A healthcare provider should evaluate the findings alongside personal symptoms, physical examinations, and other diagnostic tests to understand the complete clinical picture.
- What is CRP?
- CRP is a protein your liver makes when the body signals inflammation. Its level climbs fast and high during widespread inflammation or infection. You may have this test as a broad sign of inflammation or infection. It helps track how much there is and how it changes.
- What is a normal general inflammation blood test range?
- A typical adult range is around <10 mg/L generally considered within the normal range for conventional CRP assays; values >10 mg/L suggest significant inflammation or infection. No India-specific national reference interval is published for this parameter; your lab's printed range is the most reliable comparison. Ranges vary by lab, method and equipment — the range printed on your own report is the one that applies to your result.
