Definition

To make a blood donation is to voluntarily accept the withdrawal of one's blood by medical professionals, without asking for financial compensation. In the case of a total blood donation, once the withdrawal is performed, the separation of principal blood components is then carried out. In this way, red blood cells (or hematites), platelets, and plasma are stored until needed. Blood donation by apheresis implies the separation of cells at the moment of withdrawal, with the unnecessary cells being re-injected into the donor.
