The complete blood count (CBC) is a test that evaluates the cells that ___ (1) in blood. Blood
consists of three types of cells suspended in ___ (2) called plasma: white blood cells (WBCs), red
blood cells (RBCs), and platelets (PLTs). They are produced and mature primarily in the bone
marrow and, under normal circumstances, are released into the _____ (3) as needed.

A CBC is typically performed using an automated instrument that measures various ____ (4),
including counts of the cells that are present in a person's _______ (5) of blood. The results of a
CBC can provide information about not only the _______ (6) of cell types but also can give an
indication of the physical _______ (7) of some of the cells. A standard CBC includes the following:

·                   Evaluation of white blood cells: WBC count; may or may not include a WBC
_______ (8)

·                   Evaluation of red blood cells: RBC count, hemoglobin (Hb), hematocrit (Hct) and
RBC indices, which includes mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean
corpuscular hemoglobin _______ (9) (MCHC), and sometimes red cell distribution width (RDW). The RBC
evaluation may or may not include reticulocyte count.

·                   Evaluation of platelets: platelet count; may or may not include mean platelet
______ (10) (MPV) and/or platelet distribution width (PDW)
