There are several types of blood groups. When receiving a blood transfusion a sample is taken and sent to the lab. It needs to be matched to blood that has the same antibodies and rh factor in order for it to be transfused to a patient. There are times that even with all the necessary test causes a reaction to the person receiving blood.

Why are blood type and RH checked before a blood transfusion?
If the blood type of the donor is different from the receivers blood type, the blood type of the revive can attack the different type of blood
Will an Rh negative person who receives Rh positive blood for the first time have a transfusion reaction?
no.
What is likely to happen to a donor's cells if an Rh person who is sensitive Rh plus blood receives a transfusion of Rh plus blood?
A delayed transfusion reaction is the most likely result. Anti-D antibodies will bind to the Rh positive red cells, with subsequent removal from circulation by the spleen.
Why no reaction to blood transfusion first time to Rh negative or Rh positive blood?
because both rh positive ann rh negative the anti boby is less
Why does a transfusion reaction not occur the first time a rh positive patient is exposed to rh negative blood?
the transfusion reaction doesn't occur the first time an Rh+ patient is exposed to Rh- blood because the Rh+ patients body hasn't created the antibodies needed to attack the Rh- blood that it comes in contact with. the second time the Rh+ patients body comes in contact with Rh- blood, it will have the antibodies necessary to fight against Rh- blood.
Why is the Rh factor especially important with a transfusion?
In all the four basic blood groups there exist two sub-groups called Rh (+ve) and Rh (-ve). The people with the Rh (+ve) blood group have an additional "Rh" facto or the "Rhesus" factor (so named because it was first observed and discovered in the Rhesus monkeys). Whereas the people who do not have the 'Rh' factor are said to have Rh (-ve) blood as in B (-ve) etc. While blood transfusion it is very important to check the "Rh-compatibility" of blood of the donor and that of the recipient, because transfusion of Rh +ve blood to a person with anegative blood group leads to agglutination(clumping) of blood cells thus resulting in death of the person. But it must be noted that transfusion of Rh -ve blood to a person with positive blood group does not harm the recipient.
Why can a person with rh- blood not receive rh plus blood?
The person with Rh- blood will begin to make antibodies against Rh+ upon exposure. This may not occur with the first transfusion - but it is still not recommended to give an Rh- person Rh+ blood.
What are 2 Rh factors?
When referring to blood, you call it positive or negative. These are the two Rh factors.
Why are blood type and Rh factor checked before a transfusion?
If the blood type of the donor is different from the receivers blood type, the blood type of the revive can attack the different type of blood
What is likely to happen to a donor's cells if an Rh- person who is sensitive Rh plus blood receives a transfusion of Rh plus blood?
They will have what is called a transfusion reaction. The red blood cells will start to breakdown, the body will not get enough oxygen, the kidneys will fill up with protein from the blood, breathing will slow down or stop, and the person can go into shock and die.
Should an Rh- woman ever receive a transfusion with Rh blood?
She should not, especially if she is young or within child-bearing age. This may cause complications with future pregnancies.
