Understanding C-reactive Protein Level

A myRAteam Member asked a question 💭
Burlington, KY

This test basically shows an increase in the C-reactive protein when inflammation is present, but it doesn't tell what the inflammation is for. It could be linked to other medical conditions like coronary heart disease, diabetes, or cancer. How do I know that I'm treating the issue & not just an underlying symptom?

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.

For more detailed information, always consult with a healthcare provider.

SweetTB, it's a mystery! I have anemia of chronic inflammation according to c-reactive protein and other test results. I'm never sure I am being treated for the underlying cause of my symptoms. Frustrating!
