The drive delivers more than 50 precent of all blood donations to the PMGH Blood Bank.
As per the initiative, the CBD team visits organisations both government and non-government for volunteer blood donations.
Starting two years ago, the drive has collected about 4,000 to 5,000 bags yearly.
Nursing Officer Eddie David said the team daily gets about 50 bags but depending on the size of the organisation.
