Mentzer Index Calculator

The Mentzer Index is used to assess iron deficiency anemia by calculating the ratio of red blood cell count to mean corpuscular volume (MCV).

Input Parameters

Calculation Formula

Mentzer Index = RBC / MCV

Where:
RBC = Red Blood Cell Count
MCV = Mean Corpuscular Volume

What is the Mentzer Index?

The Mentzer Index is a laboratory test used to help diagnose iron deficiency anemia. It calculates the ratio of red blood cell count to mean corpuscular volume (MCV).

How to Use This Calculator

  1. Enter your Red Blood Cell (RBC) count in cells per microliter (μL)
  2. Enter your Mean Corpuscular Volume (MCV) in femtoliters (fL)
  3. Click the "Calculate" button to compute the Mentzer Index
  4. Review the interpretation based on your calculated value

Interpretation Guidelines

  • Normal: Less than 13 (suggests no iron deficiency)
  • Mild Iron Deficiency: 13 to 15
  • Moderate to Severe Iron Deficiency: Greater than 15

Clinical Significance

The Mentzer Index helps differentiate between microcytic anemias (small red blood cells). A high index suggests iron deficiency, while a normal or low index may indicate other causes of microcytic anemia such as thalassemia or lead poisoning.
