But what is blood?

Blood is made up of several elements. For blood transfusion, we are particularly interested in red blood cells, platelets and plasma.

Red blood cells are the most numerous cells in the blood. Their main role is to transport oxygen from the lungs to the tissues of our body and to bring the carbon dioxide produced by the cells back to the lungs for elimination.

Blood plasma carries other blood cells, nutrients, hormones and many other components that are particularly important for the proper functioning of our body.

Platelets are mainly used to prevent bleeding: they are involved in blood clotting. When a blood vessel is damaged, they form and take care of stopping the bleeding.


Red bloods cells

After donation, the red blood cells can be stored for 42 days at a temperature between 2 and 6°C. They can treat hemorrhages and severe anemia. They represent about 41% of the total blood volume.


After the donation, the plasma can be distributed "fresh", but it can also be stored for several months, frozen at a temperature of -20°C. It represents about 55% of the total blood volume.


Platelets are the most fragile part of blood. After donation, they can only be kept for up to 7 days, at a temperature between 20 and 24°C and under continuous shaking (to prevent them from coagulating). They represent about 4% of the total blood volume (with white blood cells).

How does the donation run?

During a blood donation, you will be warmly welcomed before going through simple and secure steps, allowing your precious contribution that saves lives.
