TTP is related to a deficiency of or antibody against ADAMTS13. This protease is lowered in normal pregnancy and thus is thought why TTP is more common in pregnancy. The gold standard treatment is plasmapheresis to remove antibodies to ADAMTS13

Rh Allo immunization
ritical value dependent on the laboratory, but usually ranges 1:8 to 1:32. In the case that paternity is certain and the father of the baby is available, paternal blood typing should be performed to avoid unnecessary fetal testing and procedures. If the father is Rh+, then red cell antigen genotyping should be performed to determine zygosity. If the father is homozygous, there should be no further work-up as the fetus must be Rh+ by serology and should be monitored closely. If the father is heterozygous, then amniocentesis should be performed for red cell genotyping.
