• The blood:
Blood is made up of cells (red blood cells, platelets, and white blood cells) in a protein-rich liquid (plasma). There is no blood product that can replace human blood. The fact that they are irreplaceable and perishable makes it all the more precious.
• Process of a unit of blood
A process is in place at LRC BTS for the safe collection from the donor, through the testing and processing, to delivery to the recipient.
1- Blood Collection
Before donating blood the donor fills out a questionnaire to determine his/her eligibility on that day. To be accepted for blood donation, prospective blood donors must feel healthy and well on the day of donation and must meet all requirements and criteria defined by the LRC BTS.
Blood is processed in order to prepare the blood component that the patient needs. Prior to processing into blood components, the white blood cells (also known as leukocytes) are filtered out to reduce the risk of a transfusion reaction.
The blood samples collected during the donation are sent to the testing laboratory to determine the donor’s blood type and screen for infections such as hepatitis B and C, syphilis and HIV. If a test returns positive the blood unit is destroyed and the donor is notified.
The blood products are released to hospitals
• Types of donations
Whole blood donation
A blood donation takes about 10 minutes, and around 450 ml of whole blood is collected (red blood cells, white blood cells, platelets and plasma). When you donate blood, its different components will be then separated.
From your whole blood donation, we could obtain :
- A concentrated erythrocyte (Blood red cells)
- The concentrated erythrocyte
It is intended to be transfused to a patient suffering from red cells deficit (acute anemia, bleedings)
It can be conserved for 42 days at a temperature between 2 and 6˚C.
- The Frozen Fresh Plasma
The plasma taken from your donation will be frozen at a temperature below -25˚C, and can be conserved for one year at this temperature.
Then, it will be transfused to a patient suffering from bleeding or a coagulation disorder
• List of blood components
Blood transfusion is vital to many treatments : victims of road accidents, cancers and hematological diseases, genetic diseases, bone marrow grafts, organs transplants, medicine, surgery…
Red blood cells
Their role is to transport the oxygen towards the cells and the tissues. They are used, inter alia, in cases of massive bleeding and in diseases that provoke serious or chronic anemia.
Their role is to coagulate the blood and their transfusion is inevitable for patients whose diseases (leukemia, medullary aplasia) and treatments (chemotherapy and radiotherapy) prevent the bone marrow from producing blood cells.
It is still irreplaceable. The plasma could be frozen and conserved up to 12 months. It is used for treating victims of major burns and accidents, as well as for patients who suffer from serious bleeding and some coagulation disorders.
• Some quick facts about blood
- Every person’s body contains about five liters of blood (or 10.5 pints)
- There are approximately 450 ml of blood in one unit collected
- About 100,000 new donors are needed every year to meet demand
- It can take up to 50 units of blood to save a single car crash victim
- It can take eight units a week to help someone battling leukemia
- All it takes is one donation to help save a life
Right now, somewhere in Lebanon, someone needs a blood transfusion to survive. You have the power to save their life.
