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.

Further study details as provided by Medstar Research Institute:

Primary Outcome Measures:
  • The Presence or Absence of Cell Free Fetal DNA in Maternal Blood in the Setting of a Failed Pregnancy. [ Time Frame: During initial presentation for treatment ] [ Designated as safety issue: No ]
    Percentage of participants with the presence of cell free fetal DNA in maternal circulation after miscarriage of intrauterine fetal demise

Secondary Outcome Measures:
  • The Accuracy of ccffDNA Compared to Genetic Information Obtained From Amniocentesis, Chorionic Villus Sampling, Fetal, or Placental Tissue. [ Time Frame: 3-4 weeks after specimen processing ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples With DNA
Blood collection will consist of two ten milliliters samples of whole blood in the cffDNA STRECK tube. Plasma will be retained for analysis of circulating cell free fetal DNA.

Enrollment: 50
Study Start Date: May 2013
Study Completion Date: December 2014
Primary Completion Date: January 2014 (Final data collection date for primary outcome measure)
Non-viable pregnancy
Women presenting with stillbirth, defined as fetal death occurring after 20 weeks gestation or with miscarriage, defined as fetal death prior to 20 weeks gestation.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
Women presenting to Washington Hospital Center with fetal loss would be offered DNA sequencing of cell free fetal DNA from maternal blood in addition to the standard workup for fetal demise and miscarriage as deemed appropriate by the patient's care provider. Only women with sonographic evidence of products of conception in-utero will be offered enrollment.

Inclusion Criteria:

  • Women diagnosed with Intrauterine fetal demised or missed abortion

Exclusion Criteria:

  • Patients diagnosed with threatened abortion with cardiac activity present
  • Patients with IUFD who have delivered the fetus (the induction process may already be in process, however, the fetus and placenta must be in situ at the time of blood sampling)
  • Patients with known genetic abnormalities or mental retardation as a result of chromosomal abnormalities 13, 18, 21, or sex chromosomes.
  • Children under the age of 18
  • Patients not fluent in or unable to consent to the study in English
