Hemoglobin vs RDW: Key Differences Explained
Compare Hemoglobin and RDW to learn which marker is more relevant for health assessment.
Why Compare Hemoglobin and RDW?
Comparing Hemoglobin and RDW is crucial because they are often used to assess similar yet distinct health conditions. Understanding their differences helps in selecting the right test and interpreting the results accurately.
Hemoglobin vs RDW: Which Biomarker Matters?
Hemoglobin and RDW are essential biomarkers used to evaluate different health conditions. Knowing when and how to interpret these biomarkers can significantly impact clinical decision-making.
Quick Comparison Table:
Biomarker | Purpose | Ideal Range | When to Test | Key Differences |
|---|---|---|---|---|
Carries oxygen in the blood | 13.8-17.2 g/dL (men), 12.1-15.1 g/dL (women) | Evaluate anemia or polycythemia | Low levels indicate anemia | |
Measures red cell distribution width | 11.5-14.5% | Assess red cell size variation | High in anisocytosis |
Key Takeaways:
RDW shows red cell size variation; hemoglobin shows oxygen-carrying ability.
High RDW with low hemoglobin may indicate mixed or early-stage anemia.
Use both to detect and classify complex anemia types.
