Types of Blood Donation
There are several ways to donate blood. Depending on whether a whole blood donation or a donation of specific items, sampling techniques, the equipment used, duration and frequency of donations vary. Although there are other types of blood donation, we focus on the above.
Ethics of Blood Donation
Blood donation is anonymous. This is an absolute rule that the Blood Bank / Blood Transfusion Centre must comply, particularly with regard to the recipient. Benevolent: Giving blood is free is not in any way be remunerated in any form (money, gifts, holidays). Volunteer: Giving blood is freely made without coercion. Commitment: It is a gesture of love or give it a little yourself. It's a real commitment from the heart and saves lives. This act goes beyond all barriers because it is a very human act.
Whole Blood Donation
A whole blood donation is the most common form of blood donation in which a person gives one pint of blood. After your donation, the whole blood into its components in blood bank labs. This is done as it allows Blood Bank to deliver what patients need more specifically. Your blood is made up of four life-saving components: Plasma: Plasma is 92% water, miscellaneous elements and 7% protein from which derivatives are made. Cryoprecipitate, antihemophilic factor and fresh frozen plasma (FFP) can be given to patients who have hemophilia and other bleeding problems. Gamma Globulin is used to supplement the immune system in fighting disease such as hepatitis, and serum albumin is given to treat and prevent shock.
Platelets act to induce clotting and control bleeding. White Blood Cells: White blood cells protect the body against disease and infection. They move through the blood stream to attack and absorb bacteria and other "foreign" bodies.

Red Blood Cells:
Red blood cells transport oxygen and nutrients to the tissues and remove carbon dioxide and waste. Red blood cells are indicated for more than 70% of all transfusions. Accident victims, patients with ulcers and patients undergoing surgery use red blood cells.
Blood is taken from the vein of the donor, separated into its various components using a controller. Only the donor plasma is collected in a bag containing 500 to 600 ml. Blood cells and platelets are then returned.
- A person can give 20 times a year
- From 18 years to 55 years
- An interval of two weeks is required between each donation.
- Donations of plasma can be inserted between two blood donations. It is simply necessary to observe a period of 12 weeks between donations of whole blood.
- Having a weight of at least 55 kg
- Had not taken aspirin for 3 days prior to donation.
The thrombapheresis is only to remove platelets (thrombocytes) of blood. A thrombapheresis can prepare half past one a highly concentrated suspension of platelets in the plasma. As with plasmapheresis, the donor must not have taken aspirin during 3 days before the donation.
Autologous blood donation:
This is a pre-given blood, meaning that a patient gives his own blood in anticipation of an operation. The amount of blood can be given is limited. Possibly, depending on the type of operation and the number of pints of blood that the doctor has prescribed. If it is not enough during the procedure, the physician should still use the blood of a donor. In recent years, the autotransfusion has lost its popularity due to a very large blood safety and the progress of surgical techniques for the reduction in need for blood for many interventions. For one, this method is safer without any risk.
