What is this test?
Rapid CRP measures C-reactive protein using a rapid method. CRP rises with inflammation but does not identify its cause or location.
Why might it be ordered?
- For rapid indicative evaluation in acute symptoms of infection or inflammation.
- For tracking a change when a rapid result is important for clinical judgment.
What sample is needed?
A healthcare professional collects a venous blood sample. Depending on the method, the laboratory uses serum or plasma.
How should you prepare?
Tell the laboratory about all medicines, hormone treatments, vitamins and supplements you take. Do not stop or change treatment unless your clinician tells you to. Follow any instructions about fasting and the time of collection.
How should you understand the result?
CRP may rise with many infections, injuries and inflammatory conditions. A rapid-test result may differ from a standard high-precision laboratory method. Your result is interpreted using the reference interval on the laboratory report and in the context of your symptoms, medical history and other test findings.
