To detect Rh and other blood type incompatibilities and diseases
When a mother has been previously exposed through prior pregnancies or blood transfusions to red blood cell antigens that she does not have on her own red blood cells, she may develop antibodies against those red cell antigens (become sensitized). If the antigens are present on the red blood cells of the fetus (inherited from the father), then the fetus is at risk for a maternal-fetal incompatibility. The mother's antibodies can cross the placenta and bind to and destroy the fetus's red blood cells, causing hemolytic anemia . An affected fetus can be born with hemolytic disease of the newborn . One of the most commonly encountered incompatibilities is due to ABO group differences, but there are many other blood types that may also cause this problem.
After reading about yet another who dies after childbirth, I felt the clinical need to write this article. I honestly had not heard of this before and consider myself an expert on VTE and the prevention of the occurrence. Having done some considerable work with the release of the new OB VTE Safety Recommendations with the OB team of experts, I think this condition is worthy of researching and gaining knowledge. There is really very little written on the subject and I wanted to find out the incidence as well as any alert criteria and prevention modalities that would save a future mother from succumbing from such an rare condition.
