简要总结
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.
详细描述
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.
