WBC Calculator

Formula

The formula to calculate the White Blood Cell (WBC) count is:

\[ WBC = \frac{TNC \cdot D}{V} \]

Where:

\(WBC\) is the White Blood Cell count (cells/µL)
\(TNC\) is the Total Nucleated Cell count (cells)
\(D\) is the dilution factor
\(V\) is the volume of blood sampled (µL)

White Blood Cell Definition

A WBC, or white blood cell, is a type of cell in the body’s immune system that helps fight off infections and diseases. These cells are produced in the bone marrow and are found throughout the blood and lymphatic system. They are crucial for maintaining good health and protection against illnesses. There are several types of white blood cells, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each with a specific role in supporting the immune system.

Example Calculation

Let's assume the following values:

Total Nucleated Cell Count (TNC) = 5000 cells
Dilution Factor (D) = 10
Volume of Blood Sampled (V) = 50 µL

Using the formula to calculate the White Blood Cell (WBC) count:

\[ WBC = \frac{5000 \cdot 10}{50} = 1000 \]

The White Blood Cell (WBC) count is 1000 cells/µL.
