CRP in testing refers to the measurement of C-reactive protein levels in a person's blood. This test helps detect inflammation in the body.
Understanding C-Reactive Protein (CRP)
C-reactive protein (CRP) is a protein produced by the liver. Its levels increase in the blood when there's inflammation in the body. A CRP test measures the amount of this protein to help diagnose or monitor conditions associated with inflammation. Normally, people have low levels of CRP.
Why is a CRP Test Performed?
A CRP test is typically performed for several reasons:
- Detecting Inflammation: To identify inflammation caused by various conditions, such as infections, autoimmune disorders, or injuries.
- Monitoring Conditions: To track the progress of inflammatory diseases and evaluate the effectiveness of treatment.
- Assessing Cardiovascular Risk: High-sensitivity CRP (hs-CRP) tests can help assess the risk of heart disease.
Types of CRP Tests
There are two main types of CRP tests:
- Standard CRP Test: This test measures general inflammation in the body.
- High-Sensitivity CRP (hs-CRP) Test: This more sensitive test can detect even small increases in CRP levels and is often used to assess cardiovascular risk.
What Do the Results Mean?
Elevated CRP levels indicate inflammation, but they don't pinpoint the exact cause or location. Further testing is often needed to determine the underlying condition. Normal CRP levels depend on the lab and test type, but generally, low levels are considered normal.
Here's a general idea of how results might be interpreted for a standard CRP test:
| CRP Level (mg/L) | Interpretation |
|---|---|
| Less than 1.0 | Normal |
| 1.0 - 10.0 | Mild to moderate elevation |
| Greater than 10.0 | Marked elevation, indicating significant inflammation |
Important Note: Always consult with a healthcare professional for accurate interpretation of CRP test results, as they should be considered within the context of your overall health and medical history.
