Blood bags
Type first, then the tube
Short answer
A bag of the wrong blood is not a heal. Check the card.
Also: transfusion
How it works
Blood bags need a matching type. Saline is the safer fill when you don't know. Drawing blood from a friend is a kit, not a bit.
What to do
Read the type. If you don't know, saline. Lie them down, watch the road.
Don't
Don't invent millilitres.
