How to prepare for CRP Test

Preparing for a CRP (C-reactive protein) test is generally straightforward. The test measures inflammation levels in the blood and usually does not require fasting or special dietary restrictions. However, several factors can affect results: acute infections, injuries, or intense physical exercise shortly before blood draw may temporarily elevate CRP. Certain medications (e.g., statins, NSAIDs) can also influence levels. It is advisable to inform your doctor about any medications and your current health status. While the test is often done in the morning, fasting is not mandatory. Importantly, CRP is a non-specific marker—it indicates inflammation but not its cause. The genetic tests mentioned in the context (e.g., PCSK9, PPARA) are not directly relevant to CRP test preparation. For accurate interpretation, repeated measurements and clinical correlation are recommended. Evidence: practice, based on standard medical guidelines.
