Balance hematologic : measure ?
The balance sheet hematologic, also named dial complete blood count (NFS) or complete blood count, is one of the blood tests the most common.
It is a measure of the amount of the main constituent elements of the blood : red blood cells (red blood cells carrying oxygen), leukocytes (white blood cells defending the body against pathogens), and platelets.

The blood counts
The count appearing on the balance sheet of your blood indicates the concentration of red blood cells and leukocytes in your blood. In this part is also the concentration of hemoglobin : the molecule entering the composition of the red blood cells is essential for the transport of oxygen.

The hematocrit corresponds to the proportion of the volume of rbcs relative to total blood volume. The MCV (Mean corpuscular Volume) indicates the average volume of your red blood cells and the TGMH (Content Mean corpuscular Haemoglobin), the average concentration of haemoglobin in a hématie. Finally, the CGMH (Concentration Mean corpuscular Hemoglobin) indicates the rate of hemoglobin for 100 ml of red blood cells.

The blood
There are five major types of leukocytes, including the blood indicates the concentration in your blood : lymphocytes, polymorphonuclear eosinophils, polymorphonuclear neutrophils, monocytes, and polymorphonuclear basophils. These leukocytes serve many functions in the body, for example, polymorphonuclear eosinophils to eradicate the parasites.

Balance hematologic : platelets and erythrocyte sedimentation rate
The extent of the pads is important because it is they who allow the blood to clot, stopping the bleeding in case of injury. The sedimentation rate indicates the rate of clotted blood after an hour or two spent in a tube.

Balance hematologic : is it a problem not to be in the standards ?
Beside each of your results normally include the VR (Reference Values), given as an indication only. These RV vary a lot depending on the sex and age of patients, and as a function of the laboratory in charge of analysis. A result slightly above or below expected standards, for example, is very significant.

On the other hand, if the result is significantly higher or lower than expected, there are many possible causes, benign or serious. For example : a high speed of sedimentation can be caused by an autoimmune pathology, but also by a banal flu or a pregnancy.

Another example : a low red blood cells, revealing an anemia, is often due to a simple iron deficiency but can also, more rarely, to indicate a malfunction of the bone marrow. With regard to leukocytes, their concentration can be high or low can be due to many viral infections, bacterial or parasitic. The best thing is to stay serene in the meantime the advice of your doctor.
