Weird news - Woman dies after wrong blood transfusion

Blood transfusion is a very common medical procedure, and needed for a host of services. Whether during an operation, or after an accident, or for numerous other such cases, blood transfusion is critical. However, blood is of several different types, and the body will reject blood of a different type. Hence, when going in for a blood transfusion, it is highly critical that the right blood type be selected. In this, there are some variables, some blood types are more common than the others, and some blood types can be used by others while others cannot be used - so there are terms such as universal donor, and universal recipient. However, given how routine blood transfusions are, everybody involved in this business knows what is involved and there is very little chance of error. So when an error happens, it is strange, and also deadly, such as this case in India (link to article):
