Phototherapy abo in compatibility Phototherapy is used for cord bilirubin of 3 or higher. Some doctors use it at lower levels while awaiting lab results. It has been used not only on anti-D, but on anti-E as well. If necessary, this dose can be repeated in 12 hours evidence quality Abo in compatibility This can happen if there is a miscarriage, during birth or if a mother sustains some form of trauma.

When this happens, smaller antibodies called Anti-A or Anti-B can transfer back into the baby?

As a result, these antibodies attack the baby? Babies who are affected in this way tend to become jaundiced shortly after birth.


This condition is known as Haemolytic Disease of the New Born. An exchange transfusion may be necessary.

This is when carefully measured amounts of the baby? Observation and monitoring of feeding, hydration, iron count and jaundice is best done in an environment where there is specialised staff.

Treatment Options Babies with Haemolytic Disease tend to become jaundiced very quickly after birth. This yellowing of the skin and frequently, the whites of their eyes abo in compatibility become quite obvious.

Jaundice is caused as a result of having too much bilirubin in the circulation. How is the Bilirubin Measured?

A blood test is usually collected by pricking the baby? Abo in compatibility incompatibility with transplacental transfer of IgG anti-A antibody, abo in compatibility more commonly, anti-B antibody has rarely been reported in association with intrauterine hemolysis leading to hydrops fetalis.

It should be noted that other causes of nonimmune hydrops fetalis have not been systematically excluded in these case reports.

The most likely explanation for these rare cases is that exposure to antigens similar to the A or B antigen may occur from sources other than the fetus and stimulates IgG production in the mother. For example, an antigen similar to the B antigen is found in E.

In contrast to Rh incompatibility, which tends to become more severe with each subsequent Rh positive pregnancy, ABO incompatibility does not demonstrate any consistent pattern.

Because of the rarity of abo in compatibility intrauterine abo in compatibility due to ABO incompatibility, assessment for intrauterine fetal anemia is not recommended based on the mother having type O blood.


Abo in compatibility complication of severe HDN is hydrops fetalis, in which the fetal tissues abo in compatibility swollen edematous. This condition is usually fatal, either in utero or soon after birth. In vivo, these antibodies destroy Rh D-positive fetal RBCs, but in vitro, they do not lyse cells or even cause agglutination, making them difficult to identify.

Therefore, the Coombs test is used. This test uses antibodies that bind to anti-D antibodies. The test is named for Robin Coombs, who first developed the technique of using antibodies that are targeted against other antibodies.

First, a sample of fetal RBCs abo in compatibility washed to remove any unbound antibody Ig. When the test antibodies anti-Ig are added, they agglutinate any fetal RBCs to which maternal antibodies are abo in compatibility bound.


If any anti-D is present in the mother's serum, they will bind to the cells.
