Complete Blood Count (also
known as CBC or hemogram): A series of tests which
evaluates the cellular components of blood (red blood cells, white blood cells
& platelets). Vets
often take this test to check for anaemia, infections & other health
problems.
Red blood cell count (RBC):
The number, size, shape & appearance of red blood cells in a volume of
blood.
Haemoglobin (Hb): The amount of haemoglobin
(the protein that enables the cells to carry oxygen) can be determined. The size
& shape of red blood cells is also analysed.
Hematocrit (Hct, packed cell
volume, PCV): Measures the percentage of a sample of blood which is occupied
by red blood cells.
White blood cell count
(WBC): The number of white blood cells (WBC) in a volume of blood.
White blood cell
differential: There are 5 types of white blood cells; the
granulocytes, which include neutrophils, eosinophils, and basophils & the
nongranuloctye white blood cells, lymphocytes and monocytes. The differential
determines the percentage of each type of white blood cell.
Platelet count (also called
thrombocytes): The number of platelets in a volume of blood.
Mean platelet volume (MPV): An
average size of the platelets in the blood.
