Off the top of my head, I imagine blood bag sizes are standardized, so they're easy to deal with during an emergency transfusion. It would be a nightmare to deal with containers with mixed volumes of blood. "This patient needs 3 litres of O-, let me figure out which combination of blood bags do I need now"

Donated blood is not used directly like that.

It is indeed tested and mixed.

That's why they ask so many questions about your risk of disease when donating.
