Mentzer Index Calculator
Differentiate between Iron Deficiency Anemia (IDA) and Beta Thalassemia Trait.
Mentzer Index = MCV / RBC
Result & Interpretation
Mentzer Index (MCV / RBC):
Interpretation:
Disclaimer: This index is a screening tool. A definitive diagnosis requires further testing (e.g., iron studies, hemoglobin electrophoresis).
Diagnostic Performance
Based on various studies using a cutoff value of 13, the Mentzer Index is typically associated with high diagnostic accuracy:
- Sensitivity for IDA: ~91% to 98%
- Specificity for IDA: ~83% to 93%
- Sensitivity for Beta Thalassemia Trait: ~83% to 93%
- Specificity for Beta Thalassemia Trait: ~91% to 98%
