C-reactive protein (CRP) is a protein produced by the liver that increases in the presence of inflammation in the body. Here are some key points about CRP levels:
- Normal CRP Levels:
- The majority of healthy adults have CRP levels less than 0.3 mg/dL.
- Normal values can vary slightly among different laboratories.

C-reactive protein (CRP) is a protein produced by the liver that increases in the presence of inflammation in the body. Here are some key points about CRP levels:
- Normal CRP Levels:
- The majority of healthy adults have CRP levels less than 0.3 mg/dL.
- Normal values can vary slightly among different laboratories.
- CRP Levels and Inflammation:
- CRP levels rise in response to inflammation.
- Levels from 1 mg/dL to 10 mg/dL indicate a moderate increase.
- Levels greater than 10 mg/dL are considered a marked increase.
- High-Sensitivity CRP (hs-CRP):
- This test is more precise and used to assess the risk of cardiovascular disease.
- Low risk: hs-CRP level lower than 1.0 mg/L.
- Average risk: hs-CRP level between 1.0 mg/L and 3.0 mg/L.
- High risk: hs-CRP level higher than 3.0 mg/L.
- Causes of High CRP:
- Inflammation due to various conditions such as rheumatoid arthritis, lupus, infections, heart attack, cancer, and inflammatory bowel disease (IBD).
- Testing Procedure:
- A blood sample is taken from a vein, a process called venipuncture.
- Risks associated with blood drawing include excessive bleeding, fainting, hematoma, and infection.
- Special Considerations:
- CRP levels may not be increased in people with rheumatoid arthritis and lupus, and the reason for this is unknown.
- Positive CRP results can also occur during the last half of pregnancy or with the use of birth control pills.
