Exposure to the Rh (or D) antigen. Most common in mothers who are Rh- who have a child that is Rh+. The mothers immune system will produce Rh antibodies and the blood cells of the NEXT Rh+ baby could be attacked during birth. Rh- mothers are given Rhogam to prevent this from happening. I know this is more than you asked for but every test question dealing with Rh asks something about this it is commonly called hemolytic disease of the newborn
What else can I help you with?
Which antibody and antigen combination match each blood type?
The blood type notation A Rh- indicates which antigens and antibodies are present in the blood. A indicates there are A antigens. Rh+ indicates there are Rh antigens. B antibodies. If there are A and Rh antigens but no B antigens, the antibodies in the blood plasma are B antibodies.
Can Rh antibodies of Rh- be detected?
A person who is Rh negative may have antibodies if he or she has been exposed in the past to Rh positive blood. Rhogam will prevent this sensitization in a pregnant woman with negative blood carrying an Rh positive baby.
What happen when a pregnant rh- woman delivers a rh plus baby?
The Rh factor is associated with issues in pregnancies. Rh- (Rh- negative) people do not automatically carry anti- Rh antibodies but the immune system will manufacture them if exposed to Rh+ blood. If the Rh- negative mother has not been exposed to Rh+ blood the first pregnancy will progress without complications. However upon delivering her first child the severing of the placenta from the uterus will expose the Rh- negative mother to the Rh+ blood stimulating the production of Rh+ antibodies. If the Rh- woman becomes pregnant with another Rh+ child her antibodies will traverse the placenta and obliterate the infants erythrocytes (RBCs). The baby will develop a condition known as erythroblastosis fetalis which may result in death if untreated prior to birth.
Under what conditions might a person with Rh-blood develop Rh antibodies?
The first time an Rh- patient receives blood from an Rh+ donor, the Rh- patient will develop Rh agglutinins (agglutinins=antibodies) in the blood plasma. If the patient receives another Rh+ donation, it will cause agglutination, or clumping of the blood. The red blood cell membranes become leaky and hemoglobin pours into the blood. A possible cause is kidney failure due to excess hemoglobin at filtration sites.
With a Rh plus mother and a Rh- fetus will either develop antibodies against Rh antigens?
no when Rh negative blood from the fetus interacts with Rh+ blood of the mother there will be no antibodies produced due to absence of antigen on the Rh- blood cells and when Rh positive is mixed with Rh negative blood of fetus no response is produced due to the fact that the fetus has an underdeveloped immune system
What do vaccines stimulate production of?
Vaccines stimulate production of antibodies.
Does blood type affects woman conception and bearing of chiil?
no, it is affected by your rh factor. the rh factor is either + or - as in O+ or O- the only problem is when the woman has a negative rh factor and the man has a positive rh factor. when the + and - rh factors mix, the baby may become rh positive. when the happens, the blood from the baby sometimes enters the blood of the mother. this causes antibodies to be produced, treating the baby like an intruder. this causes the mother's antibodies to break down the baby's blood. this can lead to many blood related conditions and even death of the baby. luckily there is medication that fixes this problem. talk to your doctor if you are concerned.-Akilae
Will blood type O clump or not with anti RH antibodies?
Blood type O will not clump with anti-Rh antibodies because the Rh factor is a separate antigen from the A and B antigens that determine blood type. Type O blood is characterized by the absence of A and B antigens, and the presence or absence of the Rh factor (positive or negative) is independent of the A and B antigens. Therefore, if the blood type is O and Rh-negative, it will not react with anti-Rh antibodies.
What are the sequence of events that result in erythroblastosis fetalis?
Erythroblastosis fetalis occurs when a mother with Rh-negative blood type is sensitized to Rh-positive blood through a previous pregnancy or blood transfusion, leading to the production of antibodies that attack Rh-positive red blood cells in a subsequent Rh-positive fetus. This results in hemolysis of the fetal red blood cells, leading to anemia and other complications in the fetus.
How does Rh factor affect a fetus?
When a mother is Rh negative and her baby is Rh positive, she may develop antibodies to the baby's blood that will cause it to hemolyze
Does a RH negative individual normally contain anti RH antibodies?
No. Rh-antibodies only develop in cases of pregnancy, miscarriage or a blood transfusion like if you have rh-negative blood you got AB blood. Your RH-antibodies then work to attack the foreign substance, the RBCS. In the fetus, loss of RBCS means the rise of bilburin and could eventually lead to brain damage or (kernictous), and also have low muscle tone(hypotonia)
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.
