Preterm Delivery Risk Prediction by Measurement of Prenatal Serum Screening Markers
Preterm Delivery Risk Prediction by Measurement of Prenatal Serum Screening Markers
This protocol seeks to longitudinally collect blood samples from a cohort of pregnant women.
 The biological specimens will be used to determine the predictive power of biochemical
 markers routinely used in Down syndrome screening in the assessment of patient's risk of
 preterm delivery.
The study will investigate whether the levels of individual maternal serum screening
 biomarkers, their combinations or temporal changes in the level can be associated with an
 increased risk of preterm delivery. Blood samples at three time points in pregnancy will be
 collected from the study participants. The first two blood draws will be timed to coincide
 with the first and second trimester maternal serum testing. The third blood draw will
 coincide with the screening for gestational diabetes. Pregnancy outcome information will be
 collected from the physicians and linked to the subject samples.

 Subject samples from a case-control patient group will be analyzed by the serum screening
 biochemical assay. Statistical analyses will be performed to achieve the study objectives.

 NOTE: This study is recruiting in Florida, USA. The laboratory data coordination is being
 performed in Massachusetts, USA and New Mexico, USA. New study locations will be identified
 on an ongoing basis.
