Summary

Actually, our center is doing the prenatal determination of RhD fetal genotype in all RhD negative pregnant women. The investigator want to demonstrate that this is an useful and efficient method.

Detailed description

This is a retrospective observational study that pretend to demonstrate that the prenatal determination of RhD fetal genotype is useful and efficient in our clinical practice. I'm going to check the clinical history of all negative RhD pregnant women since January 2013 until December 2015. I'll check if prenatal determination matches with postnatal RhD determination of newborn. Usually, when a RhD negative woman is pregnant we administrate gammaglobulin in 28 gestation weeks, after invasive procedures and after delivery if the baby is positive RhD. Althought, the investigators know that the 40 percent of RhD negative pregnant have a negative RhD baby. This study will do posible to know how many gammaglobulins hasn't been necessary thanks to prenatal determination. This is an important thing because gammaglobulin is an humanoid product ( it isn't without heatlth risks,...) and because is expensive. For this reason, if the investigators do universal determination of RhD fetal genotype the investigators can avoid the administration of humanoid product in pregnant women. I want to demonstrate that this practice is very useful and efficient in our population.
