Blood donation is a noble cause. You can save lives of up to three persons from one sitting of blood donation. It promotes weight loss and reduces the risk of heart disease.
Every year millions of people require blood. When a person undergoes cardiovascular or transplant surgery he/she would require blood. It is needed when people suffer from conditions like trauma care, cancer therapy, blood disorders, severe bleeding during delivery or after childbirth, road traffic accidents etc.
According to World Health Organisation (WHO), about 108 million blood donations are collected worldwide. About 50% of these blood donations come from high-income countries.
Blood donation rate is 36.8 donations per 1000 population in high-income countries, 11.7 donations in middle income countries and 3.9 donations in low-income countries.
In 2014, about 10,000 blood centres in 168 countries collected 83 million donations.
Types of blood donors
There are three types of blood donors:
- Voluntary unpaid
WHO states that adequate amount of safe blood comes from voluntary unpaid donors. It has reported an increase of 8.6 million blood donations from voluntary unpaid donors from 2004-2012. 73 countries collect more than 90% of their blood from voluntary unpaid blood donations.
72 countries collect more than 50% of blood supply from family/replacement and paid blood donors.
According to WHO, 25 countries are not able to detect donated blood for one or more infections. Blood as a whole can be used while transfusing. However, blood can be used more effectively when processed into components like plasma, red cell concentrates, etc. Notably, 111 countries have guidelines on appropriate usage of donated blood.
“Thank you for saving my life” Campaign
WHO is organizing a campaign “Thank you for saving my life” on World Blood Donor Day, which falls on 14th June, 2015. Through this campaign, it wants to thank all the donors who save lives daily by donating blood. The organization is looking forward to encourage people all over the world to donate blood voluntarily and regularly with the slogan “Give freely, give often. Blood donation matters.” The campaign throws light on the stories of the people whose lives have been saved through blood donation. This will help in increasing the blood donors in the world and encourage donors to continue blood donation.
What happens to the donated blood?
- After the blood is collected along with several small vials, it is sent to a component laboratory
- The whole blood is separated into red blood cells, platelets and plasma
- The blood is typed and labelled. This includes identifying ABO type and a positive or negative Rh factor. Thereafter, the vial of blood is tested for hepatitis B,C virus, HIV-1, HIV-2, Human T-cell lymphotropic virus, etc.
- After the blood is tested, a blood free of all pathogens and diseases is stored in large refrigerators and freezers. The blood components are packed in special-temperature controlled containers and then they are transported to various sources
Blood cannot be manufactured; it can only come from donors. Hence donate blood today. For more information, consult a family practice doctor online at eVaidya now!
