CRP Testing Essentials: Reliable, Affordable, and Clinically Relevant
1. What It Is C-reactive protein (CRP) is an acute-phase protein mainly produced by the liver into the blood in response to inflammation. CRP levels rise rapidly following inflammatory stimuli and decline promptly once the trigger resolves, making it a valuable tool for early diagnosis and treatment monitoring. Parameter C-reactive protein (CRP) Primary Site of Production Liver Clinical Utility ● Monitor inflammation and guide patient management ● Differentiate bacterial from viral infections: CRP level ≥ 50 mg/L are linked to bacterial infections in ~ 90% of cases CRP Response & Half-life ● Onset of increase: 6–8 hours ● Peak: 24–48 hours ● Half-life: ~19 hours 2. Why It Matters (1) Reliable biomarker: Clinically validated indicator of systemic inflammation, infection, autoimmune disorders, and cardiovascular risk. (2) Actionable insights: Supports differential diagnosis (bacterial vs viral), informs anti...
