CRP vs Ferritin: Key Differences Explained
Discover the differences between CRP and Ferritin to understand their health implications.
Written by
Mito Team
Introduction
While both CRP and FERRITIN are widely used biomarkers, they serve distinct diagnostic purposes. This comparison explains when to choose one or both, and how their results can guide clinical care.
What is CRP?
CRP helps detect short-term or acute inflammatory changes and is a common early-phase test in diagnostics.
What is FERRITIN?
FERRITIN provides insight into metabolic regulation or persistent health issues like dyslipidemia or systemic inflammation.
Comparison Table
Feature | CRP | FERRITIN |
|---|---|---|
Primary Function | CRP supports inflammation, immunity, or metabolic signaling. | FERRITIN indicates chronic metabolic or lipid status. |
Diagnostic Relevance | Elevated CRP flags acute immune response or flare-ups. | Changes in FERRITIN track long-term lipid/inflammatory changes. |
Speed of Response | Reactively changes within hours. | Fluctuates more slowly across days or weeks. |
Specificity | Relatively specific to inflammation or infection. | May be influenced by comorbidities or age. |
Clinical Use | Used in acute conditions and treatment monitoring. | Helps stratify risk in chronic inflammation or metabolic disorders. |
Measurement Units | mg/L or ng/mL | mg/dL or % or mmol/L |
Normal Range | Generally < 5 mg/L | Depends on patient age, sex, and test type |
Best Use Case | Detecting active inflammation, infection, or tissue damage. | Broad lipid profile assessment or long-term tracking. |
Clinical Use Cases
CRP is ordered for acute infections, trauma, or inflammation. FERRITIN is used in long-term risk evaluation or chronic disease tracking.
Pros and Limitations
CRP: High sensitivity and quick response, but can spike nonspecifically.
FERRITIN: More reflective of sustained biological trends, but slower to change.
Which Test Should You Choose?
If rapid insights into inflammation or response to treatment are needed, CRP is ideal. For broader context or chronic trend analysis, opt for FERRITIN.
Using Both Together
In many cases, clinicians order both CRP and FERRITIN to triangulate acute vs. chronic inflammatory activity and better assess overall health trajectory.
When to Test
Testing is recommended during acute illness, flare-ups, or as part of cardiovascular and metabolic screenings.
FAQs
Are these tests affected by supplements? Yes — vitamin C, iron, and statins may affect levels.
Do I need to fast? Fasting is not generally required for either.
Can I take both tests at once? Yes — they provide complementary insights.
