A positive C-reactive protein (CRP) test level indicates the presence of inflammation in the body. Specifically, a CRP level at or above a certain threshold is considered high.
Understanding CRP Levels
CRP is a protein produced by the liver in response to inflammation. Measuring CRP levels is a common way to assess the degree of inflammation in the body. Here's a breakdown:
CRP Measurement
- CRP is measured in milligrams per liter (mg/L).
Elevated CRP Levels
According to the provided reference, results of CRP tests are considered high when they are:
-
Equal to or greater than 8 mg/L.
-
Equal to or greater than 10 mg/L.
It is important to note that the specific threshold for a high CRP level can vary slightly depending on the laboratory performing the test.
High CRP Significance
- A high CRP level signifies inflammation, which can be caused by a variety of factors, including infections, autoimmune diseases, and other health conditions.
- Elevated CRP doesn't pinpoint the exact cause of inflammation but indicates its presence. Further investigation is usually needed to determine the underlying reason.
- High CRP levels can sometimes be associated with an increased risk of cardiovascular disease, though further clinical correlation is always needed to make a conclusion.
Summary Table
| CRP Level (mg/L) | Interpretation |
|---|---|
| Below 8 mg/L | Typically normal |
| 8 mg/L or greater | High, indicative of inflammation |
| 10 mg/L or greater | High, indicative of inflammation |
Key Takeaway
A positive CRP test, which shows an elevated level equal to or greater than 8 mg/L or 10 mg/L (depending on the lab), signifies the presence of inflammation in the body. It's not a diagnosis, but rather a marker prompting further investigation.
