lost a great deal of blood in the accident. However, special care must be taken in selecting new blood for you.
If the blood is too different from your own, the transfusion could kill you.
There are four basic types of blood; A, B, AB, and O. A simple test can make sure of a person's blood type.
Everybody is born with one of these four types of blood. Blood type, like hair color and height, is received from
parents.
The four groups must be transfused carefully. A and B cannot be mixed. A and B cannot receive AB, but
AB may receive A or B. O can give to any other group; therefore, it is often called the universal donor (万能捐
赠者). For the opposite reason, AB is sometimes called the universal recipient (接受者). However, because so
many reactions (反应) can happen in transfusions (输血), patients usually receive only salt of plasma (liquid
part of blood) until their blood can be matched as exactly as possible in the blood bank of a hospital. In this
way, it is possible to prevent the transfusion from any bad reactions.
