The Use of Cell Free Fetal DNA in the Maternal Blood in the Evaluation of Intrauterine Fetal Demise and Miscarriage
Women presenting to Washington Hospital Center with fetal loss would be offered participation in the study. The objective is to determine if ccffDNA obtained from maternal blood is present in the setting of missed abortion or fetal demise.
The investigators primary hypothesis is that cell free fetal DNA will be present in maternal blood in the presence of a failed pregnancy.
