Mentzer Index Calculator

Formula

To calculate the Mentzer Index (MI):

\[ \text{MI} = \frac{\text{MCV}}{\text{RBC}} \]

Where:

\(\text{MI}\) is the Mentzer Index
\(\text{MCV}\) is the Mean Corpuscular Volume (fl)
\(\text{RBC}\) is the Red Blood Cell Count (millions per microliter)

What is the Mentzer Index?

The Mentzer Index is a calculation used in hematology to help differentiate between iron deficiency anemia and thalassemia. It is calculated by dividing the mean corpuscular volume (MCV) by the red blood cell count (RBC).

Example Calculation 1

Let's assume the following values:

Mean Corpuscular Volume (MCV) = 80 fl
Red Blood Cell Count (RBC) = 4.5 million/microliter

Step 1: Use the formula:

\[ \text{MI} = \frac{80}{4.5} = 17.78 \]

The Mentzer Index is 17.78.

Example Calculation 2

Let's assume the following values:

Mean Corpuscular Volume (MCV) = 70 fl
Red Blood Cell Count (RBC) = 5.0 million/microliter

Step 1: Use the formula:

\[ \text{MI} = \frac{70}{5.0} = 14.00 \]

The Mentzer Index is 14.00.
