|For blood packs throughout the Fallout series, see Blood pack.|
Blood packs are exactly that: packs of blood used in blood transfusions before and after the Great War. They are among the worst healing items in the game, healing only +1 Hit Point upon consumption.
Blood packs are much more difficult to find in Fallout: New Vegas than in Fallout 3. They are only rarely found in first aid boxes, and can usually be found lying around medical facilities; abandoned or not.
