Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Valid and confirmed result of Rh D negative status.(one copy saved into the obstetrical records)
* Absence of actively produced anti-D antibody as shown on laboratory examination of a blood sample taken within the first trimester of pregnancy.
* Evolving pregnancy at the time of inclusion in the study ( between 8 and 26 gestation weeks as confirmed by early sonography).
* Absence of a previous invasive fetal RHD genotyping ( chorionic villous sampling, amniocentesis).
* Patient having signed an informed consent for the study.
* Inclusion and delivery expected in the same maternity ward
* Patient affiliated to a social security regimen.
Exclusion Criteria
