WHAT ABOUT THE BLOOD THAT YOU OFFER?
The blood collected from the blood donation is rarely used in this form. In most cases, it is separated into three main components (plasma, red and platelets) and transferred according to the need of the patient, which is why one unit of blood can potentially save up to three lives.
The first step of the blood donation is to check the compatibility of both the donor and the patient prior to the transfusion. In case it is compatible, a patient is given the necessary ingredient:
Red blood cells are mainly used in cases of loss of blood volume, such as accidents and childbirth and to treat anemia and other blood diseases. They are maintained at 4 ° C and must be used within 35-42 days from the day of their collection.
The plasma is used as source of coagulation factors, such as tumor or surrogate for the production of albumin (a protein used to treat burns and shock). It is maintained frozen for a period of one year.
From the sequential freezing and thawing treatment, a small part of the plasma, the cryoprecipitate is created, containing thickening agents and used as a source of factor VIII for clotting fibrinogen.
The platelets are responsible for the clotting of blood and used to treat major diseases. They should be produced within eight hours of blood samples, stored at room temperature under constant agitation, to be operated and maintained only for 5 days.
