I have been hearing of a number of incidents where people have been hospitalized and needed blood transfusions only to be told that the required blood is not available in the blood bank.... this is worrying, to say the least, should we need an urgent tranfusion (God forbid!). Advice has been to know a number of people with the same blood type who would be willing to donate in an 'hour of need'. Would it make sense for a some of us to share blood group information and contact details? Would welcome others thoughts on this topic....
