Description
The CBC test may be performed under many different conditions and to assess many different symptoms or diseases. The results can reflect problems with fluid volume (such as dehydration) or loss of blood.
The test can reveal problems with RBC production and destruction, or help diagnose infection, allergies, and problems with blood clotting.
MCV, MCH, and MCHC values reflect the size and hemoglobin concentration of individual cells, and are useful in diagnosing different types of anemia.
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 CBC test also provides information about the following measurements:
Average red blood cell size (MCV)
Hemoglobin amount per red blood cell (MCH)
The amount of hemoglobin relative to the size of the cell (hemoglobin concentration) per red blood cell (MCHC)
The platelet count is also usually included in the CBC.
