WBC vs RDW: Key Differences Explained
Compare WBC and RDW to learn which marker is more relevant for health assessment.
Why Compare WBC and RDW?
Comparing WBC 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.
WBC vs RDW: Which Biomarker Matters?
WBC 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 |
|---|---|---|---|---|
Counts white blood cells | 4,500-11,000 cells/µL | Detect infections or inflammation | High count indicates infection | |
Measures red cell distribution width | 11.5-14.5% | Assess red cell size variation | High in anisocytosis |
Key Takeaways:
WBC reflects immune health; RDW shows red cell size variation.
High WBC with elevated RDW may occur in inflammation or infection with anemia.
Use both to assess complex cases involving infection and nutrient imbalance.
