The American Red Cross collected hundreds of thousands of blood donations ......may discard as many as 1 of every 5 donations

Blood is a commodity with a limited shelf life. If they collected hundreds of thousands of units and managed to put 4 out of every 5 of them to use, that's a pretty decent record.

You are right about the shelf life but I hate that they "sold" some of the blood to hospitals and pocketed the profit.

Same people that bitch about an 80% efficency rate with the Red Cross are more than willing to fork over thousands in tax dollars to a government that probably hasn't hit the 20% mark in most programs.
