A complete blood count (CBC) test measures the following: The number of red blood cells (RBCs; The number of white blood cells (WBCs; The total amount of hemoglobin in the blood; The fraction of the blood composed of red blood cells (hematocrit; The mean corpuscular volume (MCV) - the size of the red blood cells. CBC also includes information about the red blood cells that is calculated from the other measurements: MCH (mean corpuscular hemoglobin; MCHC (mean corpuscular hemoglobin concentration. The platelet count is also usually included in the CBC.

One of the most commonly ordered clinical laboratory tests, a blood count, also called a complete blood count (CBC), is a basic evaluation of the cells (red blood cells, white blood cells, and platelets) suspended in the liquid part of the blood (plasma). It involves determining the numbers, concentrations, and conditions of the different types of blood cells.

A complete blood count (CBC) is a series of tests used to evaluate the composition and concentration of the cellular components of blood. It consists of the following tests: red blood cell (RBC) count, white blood cell (WBC) count, and platelet count; measurement of hemoglobin and mean red cell volume; classification of white blood cells (WBC differential); and calculation of hematocrit and red blood cell indices .

The clinical laboratory test that evaluates the three main cellular components of peripheral blood (red cells, white cells, and platelets) is called the " complete blood count " (CBC). It is used commonly to assess whether a patient is anemic (low red cell count), has an infection (increased white blood cells), or has abnormal blood coagulation (platelet levels).
