Importance of Blood Donation

Emergencies occur every minute, and blood is the most important component that is required during the treatment. Whether it is accidental injuries, burns, diseases, children suffering from ailments like Thalassaemia, bleeding disorders, Leukaemia, Blood Cancer, all require blood. Accidental injuries require blood during operation when a huge amount of blood is shed from the body. Also, in various types of major or minor surgical operations, blood is required for transfusion. The unavailability of blood may cost lives. Hence, the importance of blood donation is tremendous. This is the greatest gift one can give to fellow humans. Voluntary blood donors are saviours of mankind. If someone really loves and cares for oneself, the only way to express it is to donate blood voluntarily. Moreover, safe blood transfusion comes under legal protection as it is life-saving.

Role of Blood in Body

The role of blood in the human body is unique. Blood is made up of several useful components such as Red Blood Cells, White Blood Cells, Platelets, Plasma and selected Plasma Proteins. These components perform special functions in the body. Red Blood Cells (RBC) transport oxygen throughout the body; White Blood Cells (WBC) constitute the body’s defence mechanism; Platelets help in stopping bleeding, and plasma transports proteins, including antibodies. Blood also evacuates waste products from all organs of the body.

Each of these components can be separated from the donated volume of blood and transfused into a patient depending upon the requirement. Thus, many can benefit from one unit of blood.

There are four main blood groups, i.e. A, B, AB and O. Group O is the most common blood group found in human beings, and therefore, it is mostly in demand.

About Blood Donation

Blood donation is safe and simple. It takes approximately 10-15 minutes to complete the blood donation process. The average amount of blood present in an adult is 4-5 litres, or about 8% of the body weight. The body is constantly generating new blood cells. A person can donate blood 168 times during the ages of 18 to 60 years. The quantity of blood present in 1 kg of body weight is 76 ml for males and 66 ml for females. Out of this 8 ml/kg body weight is donatable. Males can donate blood after every 3 months while females after every 4 months.

Blood collected from voluntary donors are stored at blood banks, and it will be readily made available to needed patients on a replacement basis. Fear of needles, fear of pain, fear of the sight of blood, fear of future weakness, fear of possible ill effects, objection from elders, ignorance and illiteracy etc., are all reasons for many people who are hesitant in donating blood. All these myths and misconceptions are vanishing from society with the help of education and knowledge.


Every year countries around the world celebrate World Blood Donor Day on 14th June. The event is conducted to raise awareness for blood donation. It is also celebrated to thank voluntary and unpaid blood donors for their life-saving gifts of blood.
