In order for a victim to receive the correct medical attention emergency medical professionals must know their blood type. Not all blood types can receive different blood types. AB blood type is the universal recipient, this is because they lack both A and B proteins making it possible to receive both type A or B blood. Red blood cells makes it not possible for certain blood types to receive certain types of blood. For example, type A cannot receive type B blood. And type B cannot receive type A blood. Looking at blood stains at the crime scene and processing them can also help find a suspect. For example, a suspect could have their victims blood on their clothing or shoes detecting crucial trace evidence. I am now curious as to what blood type I am and how common my blood type is. I find it interesting how people donate blood in order for people to receive the medical attention they need.
