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 is Rh factors checked before a transfusion?
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.
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.
Will an Rh negative person who receives Rh positive blood for the first time have a transfusion reaction?
no.
Is their such a thing as blood d?
I assume what you are talking about is D antigen in Rh (Rhesus) blood group system. Rh blood group system is the most important blood group system after ABO blood group system (i.e. type A (AA, AO), type AB, type B (BB, BO), type O (OO) ). The Rh blood group system consists of 50 defined blood-group antigens and the 5 antigens D, C, c, E, and e are the most important. The commonly-used terms Rh factor, Rh positive and Rh negative refer to the D antigen only. Rh factor (Rh- and Rh + depending on D antigen neg/pos) is important for blood transfusion and prevention of hemolytic disease of the newborn or erythroblastosis fetalis (basically the baby and mom have different blood type - Rh- and Rh+ and cause severe immune response - fatal to the newborn)
Technique of exchange transfusion in jaundice what should be the blood group and rhesus factor to be used for exchange transfusion in a group a rhesus positive baby of a rhesus negative mother?
If the baby has already been born then you can transfuse A RH POS to the baby. If the baby is still in the womb I would think A RH NEG would be right.
Rh positive mother a positive baby?
If a person has the Rh factor, then they are positive. If they don't have the Rh factor, they are negative. The Rh factor is dominant, so a mother with it would have an Rh positive baby even if the father is negative for the Rh factor.
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.
Do only women have to be concerned with the Rh factor?
No, both men and women should be concerned with the Rh factor. The Rh factor is a protein found on red blood cells, and it can cause complications during pregnancy if a woman is Rh-negative and her partner is Rh-positive. It is important for both partners to be aware of their Rh status to prevent such complications.
How is it that an incompatible ABO blood group will generate a transfusion reaction the first time a transfusion is given while Rh incompatibility creates a problem the second time?
The antigens of the ABO system are mimicked by bacterial cell walls. So if your body does not actively suppress antibodies to them (because you have them) then antibodies will form over time to the ones you so not have (A or B or both). The rhesus factor (Rh) is not mimicked in nature and so antibodies are not formed in Rh negative people until after an exposure - usually when an Rh negative women carries an Rh positive child. If the person is Rh positive then antibodies will not form no matter what.
What are Rh Factor?
Rh factor is a blood protein. About 84% of the population is Rh positive, meaning only 16% of the general population is lacking Rh factor (RH negative).
