Bihar would soon have a database of state-level blood donors to boost voluntary blood donation and reduce the expenses on maintenance of blood in blood banks, according to Bihar State Aids Control Society. Society's Project Director Sanjiv Kumar Sinha told reporters that the process of database of blood donors would begin soon as there has been significant rise in number of blood donors in Bihar during the past five years. "Now now we will register the persons desirous to donate the blood to make the database.. we will open up a club of such donors," he said. Sinha said the new system would help reduce the cost on maintenance and test of blood in blood banks and will also not not allow wastage of blood. He laid stress on intensive campaign for voluntary blood donation and noted that against national average of 62 per cent of donation of blood, Bihar records on an average 38 per cent voluntary blood donation. According to the Figures available, during 2006-07, 53,592 units of blood were collected, but there was marked improvement in collection which went up 1.16 lakh units during 2010-11, he said.
