Every year June 14th is celebrated as world blood donor day, to increase the awareness to save blood and blood products, to encourage more people to donate blood, to decrease the myths related to blood donation and surely to thank all the blood donors for their voluntary, life saving gifts of blood. World blood donor day is marked by world health organization (WHO). This day is celebrated every year on the day of birthday anniversary of Karl Landsteiner which is of 14th of June in 1868. This event celebration was first started in the year 2004 aiming to raise the public awareness about the need for safe blood donation (including its products) voluntarily and unpaid by the healthy person. Theme of 2017 is "Give Blood, Give Now, Give often". In 57 countries, which are mostly high-income countries 100% of the blood is collected from volunteer, unpaid donors. But some countries still depend on family members or paid donors for the blood.
Every unit of blood can save 3 lives. So if a person starts donating blood at age 18 and donated every 90 days until you reached 60, you would have donated 30 gallons of blood, potentially helping save more than 500 lives. But there is still a shortage of 2.5 million liter of blood in India. The shortage of blood in 2015 has come to 9%, from 14% in 2014. Blood donation doesn't have any outcome or people will not have any shortage of blood in the near future. Blood only contribute 9% of our blood weight blood donation will not shoe any dizziness and weakness. And new syringe are used for every blood donor, and remove the chance of any communicable disease.
There are 4 components in blood, which are red cells, platelets, plasma and cryoprecipitate. Among them except cryoprecipitate all other components can be derived from a unit of blood. So, one unit blood can save 3 lives. Blood can be donated as a whole or only by components. Eight weeks should be kept between every donation, as red blood cells take 6-8 weeks to replenish, but plasma takes only 24 hours to replenish the given amount. Any person donating blood will not any shortage of his/her own blood in the future. People with O negative blood are universal donor, as this blood doesn't contain any protein and doesn't have any chance of rejection by the blood. But this blood is very rare, only 6.6% population in the world have this blood.
Blood donors should be of minimum age of 18 years and with a minimum weight of 50 kgs. The donor should not have any communicable disease in his/her blood such as HIV, aliment of diabetes or cancer, tuberculosis, asthma or rabies and the blood hemoglobin should be of 12.5g/dL. Person should not have a low blood pressure or high blood pressure.
