RH factor is a protein on some peoples red blood cells. RH disease, or RH incompatibility, occurs when an RH-negative mother is pregnant with an RH-positive baby. Learn how RH disease affects your baby and how to prevent it.
Anti-D therapy has no direct benefit to the woman but is designed to promote fetal health in future pregnancies. The ethical (and legal) basis for current policy and practice is that women should be given appropriate information about Anti-D Ig so that they are in a position to give consent to the treatment. But on what basis are women able to make such a decision when the RhD blood group of their fetus remains unknown? Introduction of fetal RHD genotyping to prevent unnecessary administration of Anti-D Ig would be more consistent with existing policy which is aimed at reducing wasteful use of blood and blood products and ensuring that the right product is given to the right person [20]. Moreover, while a recently published cost analysis of mass fetal RHD genotyping suggested that the costs of introducing such a service would not be met by the reduction in use of prophylactic antenatal Anti-D Ig, [21] others have argue that automated testing lowers assay costs below the price of Anti-D Ig and is ...
If you just found out youre pregnant, one of the first tests you should expect is a blood-type test. This basic test determines your blood type and Rh factor, which may play an important role in your babys health.

Objectives: 1) To determine risk factors for fetomaternal hemorrhage. 2) To identify a cost-effective method to detect fetomaternal hemorrhage prior to significant fetal anemia.. Significance/Background: Fetomaternal hemorrhage (FMH) is a condition in which occurs when the placenta transfers blood from the fetus to the mother. Normally, nutrition and gasses pass from mother to baby through the placenta and only waste products pass from baby to mother through the placenta. Whole blood cells do not normally cross the placenta in significant amounts. Mild FMH, where a small amount of whole blood passes from fetus to mother but does not hurt the mother or baby, occurs in about 75% of pregnancies. A pregnant woman does not know this occurs. It is only discovered if a special blood test that is labor-intensive to perform and difficult to interpret called the Kleihauer-Betke acid elution test is done. As mild FMH hurts no one, this test is not part of routine care. In most cases, testing is done only ...

TY - JOUR. T1 - Identification of alloreactive T-cell epitopes on the Rhesus D protein. AU - Stott, L M AU - Barker, R N AU - Urbaniak, S J PY - 2000. Y1 - 2000. N2 - Although considerable effort has been devoted to characterizing alloantibodies specific for the Rhesus D (RhD) blood group antigen, virtually nothing is known about the helper response that drives their production. Therefore, the aim of this study was to map alloreactive T-cell epitopes on the RhD protein. Peripheral blood mononuclear cells (PBMCs) were obtained from 22 RhD-negative volunteers in whom anti-D alloantibodies had developed after deliberate immunization or RhD-incompatible pregnancy, The PBMCs were stimulated with a panel of up to 68 overlapping synthetic 15-mer peptides Spanning the complete sequence of the RhD protein. One or more peptides elicited proliferative responses by PBMCs from all 22 of the alloimmune volunteers but from only 2 of 8 alloantibody-negative control donors. Proliferation of PBMCs from the ...

You might ask about the other blood groups: Rhesus negative and the like. The difference is that we dont have naturally occurring antibodies against these; we have to be sensitized. Sensitization is caused either by a previous transfusion or a previous pregnancy. The Rhesus blood groups have 5 separate antigens: c, C, D, e and E. There is no d. We normally only test for D as anti-D is the commonest acquired antibody. Consequently, we give Rhesus D negative blood to Rhesus D negative patients and give anti-D injections to Rhesus D negative mothers who have Rhesus D positive babies, to prevent sensitization. But patients do get sensitized against c, C, e and E, and against a range of other less well known antigens such as Kell and Duffy. Cross matching is done to screen out incompatibilities here, but a sensitized patient may have no detectable antibody, only producing it after re-stimulation by a transfusion. The antibodies produced then slowly (or sometimes not so slowly) destroy the transfused ...

Each person falls under one of the four blood types, A, B, AB or O, and has either a positive or negative Rh factor which determines their blood cells characteristics. If a person is Rh positive, it means that they are carriers of the Rh factor protein, and those who are Rh negative are non-carriers. Rh disease occurs when the mothers blood type is incompatible with that of her baby, and even though Rh incompatibility doesnt usually pose a problem during the first pregnancy, if the mothers and babys blood intermingle during labor the mothers body will register the babys Rh protein as a foreign substance and will attempt to destroy it by producing antibodies, which could critically threaten the babys wellbeing. That is why an Rh status blood test is usually conducted after the 28th week of pregnancy to check for antibodies and determine whether you need to be given an Rh-immune globulin injection if you are Rh negative. ...

Initially, if in the event when the blood of a RhD-Negative mother and RhD-Positive infant mix, the mothers body produces the IgM (not IgG which passes through the placenta) antibody in response to the red blood cells that appear foreign to her body (because they lack the RhD antigen). It is crucial to note that the IgM protein can not cross the placenta. It is in subsequent pregnancies, a repeat encounter with the Rh D antigen which stimulates the rapid production of the IgG anti-D. This antibody is then transported across the placenta and enters the babys circulation marking the red blood cells to be destroyed. [2][4][5][6] ...

A rhesus D positive baby in a rhesus D negative mother can cause her circulation to produce anti-D IgG antibodies (isoimmunisation) if foetal cells leak into the maternal circulation which may happen at delivery and in trauma even mild in severity. Tests for D antibodies are done in all Rh-ve mothers at booking, 28 and 34 weeks gestation. Anti-D immunoglobulin is routinely given antenatally at 28 weeks and 34 weeks. Rhesus haemolytic disease is a disease that can vary in severity from mild anaemia to hydrops fetalis or still birth. The Rhesus D antigen has been found to be well established in a 6week old foetus [Murphy] and although the foetus at that age is protected to a large extent by the pelvis the chance of foetal blood leaking into the maternal circulation in the event of an abdominal trauma is highly likely and may infact occur before the standard administration at 28 weeks. Once antibody formation has occurred the administration of anti-D is ineffective so any delay in administering it ...
Rh negative women who deliver an Rh positive baby are at risk of developing anti-Rh antibodies.1 Rh positive babies born of these mothers will develop Rh haemolytic disease. This is a severe condition responsible for death in utero or in the neonatal period or severe jaundice with ensuing brain damage. The natural history of the disease has not been described in recent literature. Walker,1 in 1971, reviewed a series of cases from his community. It was found that 14% of affected pregnancies resulted in stillbirths. Of the survivors, 30% had severe disease almost certainly fatal without treatment, while an additional 30% had moderate disease which would manifest as severe hyperbilirubinaemia that untreated may result in brain damage and/or death. Forty per cent of cases would require no treatment. Therefore, it can be estimated that approximately 50% of children with untreated haemolytic disease of the newborn (HDN) will die of the disease or develop brain damage. Similar observations were made in ...

Rh incompatibility is caused by destruction of fetal erythrocytes from transplacental passage of maternally derived IgG antibodies. IgG antibodies are produced by the maternal immune system, usually against the rhesus D (RhD) antigen. These antibodies can freely cross the placenta, binding to and destroying RBCs. More than 50 known RBC antibodies potentially cause Rh incompatibility. The consequence is progressive fetal anaemia, which may ultimately lead to hydrops fetalis (collection of fluid in serous compartments) and death. [1] Hadley AG.

Rh blood type is especially important for pregnant women. A potential problem arises when a woman who has Rh-negative blood becomes pregnant with a baby (fetus) that has Rh-positive blood. This is called Rh incompatibility. If the blood of an Rh-positive baby mixes with the blood of an Rh-negative woman during pregnancy or delivery, the mothers immune system produces antibodies. This antibody response is called Rh sensitization and, depending on when it occurs, can destroy the babys red blood cells.. Rh sensitization does not usually affect the health of the baby during the pregnancy in which the sensitization occurs. However, the baby of a future pregnancy is more likely to be affected if the babys blood type is Rh-positive. Once sensitization has occurred, the baby can develop mild to severe problems (called Rh disease, hemolytic disease of the newborn). If untreated, complications from sensitization can, in rare cases, lead to the death of an Rh-positive baby.. An Rh test is done in early ...
