What This Test Measures
This test measures the quantitative level of C-reactive protein (CRP) in your blood. CRP is a protein produced by your liver and released into the bloodstream during infections or injuries as part of an inflammatory response. Because this test is quantitative, it reports a specific measured concentration of CRP rather than a simple positive or negative result.
CRP itself is not a specific disease marker. Elevated CRP reflects the presence of inflammation in the body, which can result from infections, injuries, or certain chronic and autoimmune conditions. This test measures CRP levels directly, not any other inflammatory marker, and does not identify the underlying cause of inflammation on its own.

FAQ
1. What is the purpose of this test?
This test measures the quantitative level of C-reactive protein (CRP) in your blood. CRP rises when your body experiences inflammation, often due to infection or injury. The measurement may help a healthcare provider evaluate the presence and relative severity of inflammation, though it does not identify the specific cause on its own.
2. Who would benefit from this test?
This test may benefit individuals experiencing symptoms of an acute infection, such as fever or chills, whose provider wants to evaluate inflammation. It may also suit people already diagnosed with an infection or a chronic condition who want to track CRP levels during treatment.
3. When should I order this test?
You might consider ordering this test if you are experiencing symptoms associated with acute infection, such as fever, chills, or shortness of breath. It may also be useful if you have an existing infection or chronic condition and want to monitor CRP levels alongside your provider's guidance.
4. What does this test measure?
This test measures C-reactive protein (CRP) directly in your blood and reports a specific quantitative concentration. It reflects the presence and relative level of inflammation but does not indicate its cause. This test measures CRP only, not any other inflammatory marker or antibody.
5. Do I need to fast before this test?
No special preparation is required for this test. You do not need to fast beforehand.
6. How quickly will I get results?
Results are typically available in 1-3 days. Turnaround may take longer based on weather, holidays, or other lab delays.
7. How do I interpret the results?
The meaning of your CRP result depends on your symptoms, medical history, and other clinical context. An elevated CRP level does not by itself confirm a specific condition, and a normal level does not rule one out. Your healthcare provider will consider this result alongside your symptoms and any other relevant testing.
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
8. What should I do if my results are abnormal?
If your CRP level is outside the expected range, review the result with a qualified healthcare provider. They can help determine whether additional evaluation or testing is appropriate based on your symptoms and history. This result alone does not provide a complete clinical conclusion.
9. How often should I get tested?
Testing frequency should be determined as directed by your healthcare provider, particularly if you are monitoring an existing infection or chronic condition. There is no fixed repeat testing schedule associated with this test.
