Red blood cells (RBCs) are the most numerous cell type in the blood (4.8-5.4 million RBCs/mL of blood). The cells are modified structurally to carry oxygen. The cells are biconcave disks approximately 8 µm in diameter (a doughnut without a hole) with no nucleus or metabolic machinery. The absence of cellular organelles allows the internal space of the cell to be available for O2carrying. The interior of the RBC is filled with Hemoglobin (Hgb), a protein that functions primarily to carry O2. A typical RBC has approximately 280 million Hgb molecules in it due to the lack of cellular organelles.

The count may be expressed in one of several different types of units because there is variation depending on which unit of measurement a particular lab uses. Different labs will also have their own definition of what constitutes a "high" or a "low" WBC count.

What this all boils down to is that while a table of WBC counts, and the high and low values, is included below for reference, the numbers are an example of only one way of showing how a normal count might be defined.
