Identified :: Blood Transfusions

If blood between two humans is mixed improperly, it could very well end up fatal. Because all types of blood are different, as explained in the last section, they hold different amounts of proteins, carbs, and other substances that keep the body running. The mixing of blood gone wrong could end up in a deadly clot, or it could severely mess up red blood cells, which would stop the flow of oxygen through the body. Both of these could easily end up with death.

Another problem with transfusions is that the donor could be giving away deadly diseases through their blood, such as AIDS. There was a movie I saw once, called "The Cure", about a kid who had a blood transfusion done to him. Through that transfusion he was given AIDS. Him and his friend went on a quest to find a cure for AIDS, and it obviously came up unsuccessful. But this is a prime example of how blood transfusions could go wrong.
