Blood donations are conducted by organising blood donation camps and it has led to reduce the gap of demand and supply of blood. Many people come forward to donate blood voluntarily for storage in blood bank and use for those who are in dire need. It is the perfect way to cater to the demand of blood. The first blood bank was established in Kolkata in March 1942 at the All India Institute of Hygiene and Public Health and was managed by the Red Cross. That tradition goes on. We organise blood donation camps with Govt. blood banks. Majority of this blood is used to help out the underprivileged.
