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.
What else can I help you with?
Why there is no reaction against Rh factor on first transfusion?
There is no reaction against the Rh factor during the first blood transfusion because the recipient's immune system has not yet been sensitized to the Rh antigens. When Rh-positive blood is transfused into an Rh-negative individual for the first time, their body does not have pre-existing antibodies against the Rh factor, allowing the transfusion to occur without an immediate immune response. However, if an Rh-negative person is exposed to Rh-positive blood again, their immune system may recognize the Rh antigens and mount a reaction.
Why is the Rh factor especially important with a pregnantcy or a transfusion?
The Rh factor is crucial in pregnancy and transfusions because it determines blood compatibility. If an Rh-negative mother carries an Rh-positive fetus, her body may produce antibodies against the fetus's blood cells, leading to hemolytic disease of the newborn. In transfusions, receiving Rh-positive blood can trigger an immune response in an Rh-negative recipient, potentially causing serious complications. Therefore, knowing a person's Rh status helps prevent these dangerous situations.
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.
Do erythrocytes contain rh factor?
Yes, erythrocytes (red blood cells) can contain the Rh factor, which is a specific protein on their surface. The presence or absence of the Rh factor distinguishes between Rh-positive and Rh-negative blood types. If an individual has the Rh factor, they are considered Rh-positive; if they lack it, they are Rh-negative. This classification is important in blood transfusions and pregnancy.
Will an Rh negative person who receives Rh positive blood for the first time have a transfusion reaction?
no.
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.
What does the initials rh stand for in blood types?
The initials "Rh" stand for Rhesus factor, which is a protein found on the surface of red blood cells. This factor is important in blood typing, as individuals who have the Rh protein are considered Rh positive (Rh+), while those who do not have the protein are considered Rh negative (Rh-).
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)
What are Rh Factor?
The Rh factor is a protein that can be present on the surface of red blood cells. If someone has the Rh factor on their red blood cells, they are considered Rh positive. If they do not have the Rh factor, they are considered Rh negative.
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.
