Giving Red

Blood donation is a noble act that can save many lives; one in four people who enter hospitals in the UAE need blood transfusions. Giving blood is not only a great way to help others in need; it will also make you feel very good about yourself. One unit of blood can save up to three lives. The blood can be divided into several components (red blood cells, plasma, and platelets) which go towards helping patients with different ailments such as anemia, haemophilia, and many types of cancer.

 

Blood is made up of three main components that serve various purposes.
 

Red blood cells give blood its colour and makes up for 40% of its volume. The main function of RBCs is to transport oxygen and carbon dioxide to and from the cells. They have a shelf life of 42 days when they are stored in refrigeration. Transfusions of red blood cells are used to treat people with severe anemia, those who experience severe bleeding (such as accident victims) and those whose red blood cells do not function adequately.
 

Plasma is the straw coloured liquid that makes up the rest of the blood. It contains very important nutrients and clotting factors that are vital to a person’s health. Three litres out of the five litres of blood in an average adult’s body is made up of plasma, which can be divided into 17 different products. It can be stored frozen for up to 12 months and can assist patients with life-threatening conditions and haemophilia.
 

Platelets assist in the blood clotting process. They are tiny fragmented cells that prevent blood loss by covering up tears in blood vessels. They can only last up to 5 days and so it is vital that they are donated frequently. Platelets are primarily used to treat cancer patients; diseases such as leukemia and medical treatments such as chemotherapy lower platelet counts and this can cause spontaneous bleeding which is dangerous and possibly fatal (if it occurs in the brain).
 

Know your blood type

Although everyone has the same components in their blood, the presence of A and B antigens (substances that can trigger immune responses) decides what blood type a person has. Knowing your blood type is vital, not only in case of emergencies, but also because it helps determine which type of donation is the best use of your blood.
 

Group A
Blood has only the A antigen. The need for type A whole blood and plasma/platelets is always high, and so it is useful to donate as often as possible.
 

Group B
Blood has only the B antigen. The most useful component in type B blood is the plasma, as it can go towards helping burn victims and people with severe diseases.
 

Group AB
Blood has both A and B antigens. AB plasma can be given to any patient, regardless of blood type, and is always in high demand.
 

Group O
Blood has neither A nor B antigens. People with O positive/negative are most common and so all donations are valuable.
