Complete Blood Count
(CBC)

Complete Blood Count Overview

The complete blood count (CBC) is one of the most commonly ordered blood tests by doctors. To understand this test, it is important to know that the blood generally consists of two major parts: plasma and cellular elements. The plasma is the part of the blood that is liquid which allows the blood to flow easily. The other part of the blood consists of blood cells or cellular elements.

The major cells in the blood are white blood cells (WBC), red blood cells (RBC), and platelets. Each of these types of cells carries out specific and important functions.

The complete blood count test measures the quantity of all the different types of cells in the blood. It also provides some valuable information on other parameters related to each type of blood cell.
