The blood is irreplaceable!

Blood is not artificially reproducible and is indispensable to life. 
Blood is a fluid tissue composed of cellular elements (red blood cells, white blood cells and platelets) and a liquid (plasma) element, in which are dissolved proteins, mineral salts, fat and sugars. 
Based on particular substances on the surface of red blood cells, blood differs in four basic types: group A - group B group AB - group O (zero); each of these groups is defined as positive or negative according to whether or not the "Rh factor" is present.

To give blood you must be at least 18 years old, weigh over 50 kg and be in good health. 
For full blood donations you must not exceed 65 years of age; for plasma and platelet donations the limit is 55 years of age

Some types of donation:

Whole blood

Plasma ( Plasma Plasma)

Plates (piastrinoaferesis) -


 Whole blood donation

Whole blood sampling is absolutely harmless to the donor and lasts about 5-8 minutes. The maximum volume of blood drawn, established by law, is equal to 450 cubic centimeters +/- 10%. After the withdrawal, the donor is offered a good refreshment to replenish liquids, sugars and nutrients. Employees receive a paid retirement day. 


Plasmaferes: plasma donation

What is plasma

Plasma represents the liquid component of the blood, which allows the blood cells to circulate. The plasma is predominantly water (over 90%), in which many substances such as proteins, sugars, fats, mineral salts, hormones, vitamins, antibodies and coagulation factors are dissolved and transported.

In the haemorrhage (Greek term meaning the act of "taking away"), through the use of cellular separators, only the blood component of the donor is obtained from plasma (plasmapheresis) or platelet (platelet infestation ), returning the remaining elements simultaneously.

The plasmapheresis is performed with equipment that draws blood and separates the components, returning the cells to the donor in a continuous process, through a single venous access.

This donation has a duration varying from 35 minutes to about 50 minutes, preferably by appointment and since specific equipment (cellular separators) is needed at authorized transfusion facilities.

Plasma donation requirements are similar to those for the whole blood donation. The interval between a donation and the other of plasma alone can be only 14 days because the plasma regenerates very quickly without any consequences or negative repercussions.


Piastinapheresis: platelet donation

The platinum absorber consists in the sole withdrawal of platelets. In addition to the requirements for blood donation, the platelet donor should have a normal haemocoagulatory condition.

It can be carried out by centrifugation using a few cycles during which the equipment used separates the corpusculous part of blood from the plasma; the latter is collected in a satellite bag waiting to be returned to the donor. From the corpusculated part, the platelets that are collected in a special bag are automatically extracted, without possibility of contamination, by a closed loop.

The cycle ends with reinfusion to plasma donor, red blood cells and white blood cells. At this point, the new cycle begins until the required number of platelets reaches. Normally more than 6 piastrinoferers per year can not be performed; the minimum allowable interval between two platelets and between a platelet and a whole blood donation is fourteen days, while between a whole blood donation and a platelet infusion is one month. All the procedure takes about an hour and a half. The collected platelets will be used within 5 days of withdrawal for the treatment of some serious illnesses such as leukemia,
