The CBC

CBC stand for Complete Cell Count.....Almost every person at least more than once had a CBC done. The CBC gives the doctor detailed information about what is going on in the blood. There is two main lines of cells; White blood cells (leukocytes) and Red blood cells (erythrocytes). White blood cells had a wide range of functions primarily as defense mechanism against diseases and red blood cells are in charge of the trasnportation of oxygen to organs and tissues.
This is the information content in a CBC;
WBC = White blood cell count ( Normal range: 4,000 to 10,000)
RBC = Red cell count ( Normal range; 4 to 5 million)
PLT = Platelets (Normal range: 150,000 to 350,0000)

Platelets function is related with the coagulation.

Other information content in the CBC:
MCV = Mean Cell Volume ( provide information about size of the cell).
MCHC = Mean Cell Concentration Hemoglobin
MCH = Mean Cell Hemoglobin ( provide information about content of hemoglobin on the cell).
HGB = Hemoglobin ( protein that bind O2 and carrie it on the RBC) Normal - 11-13
HGB vary depending on the sex
HCT = Hematocrit ( ratio of red cell volume on whole blood) Normal - 36% a 45%
RDW = Red Distribution Width ( provide information about variation in sizes of the RBC) Normal = 12 a 17%

Later I will discussed why this information is useful and how results can demonstrate some kind of diseases.
