Cohort study 

研究目的:

评估本中心辅助生殖ART可能影响一些的生理参数与检测指标,讨论ART孕妇是否可以安全地使用无创胎儿非整倍体检测NIPT进行产前筛查,有无检测性能的降低,继而分析何种干扰因素可能导致检测稳定性或分析有效性产生变化。以期探讨ART对NIPT检测结果的影响,为临床医生提供重要的信息,对于评估ART孕妇的胎儿染色体异常风险具有重要的价值与意义。  

Objectives of Study:

To evaluate some physiological parameters and detection indicators that may be affected by assisted reproduction ART in our center, discuss whether pregnant women with ART can safely use non-invasive fetal aneuploidy detection NIPT for prenatal screening, whether there is a decrease in detection performance, and then analyze what interference factors may lead to changes in the stability of detection or the effectiveness of analysis. In order to explore the effect of ART on NIPT test results, provide important information for clinicians, and have important value and significance for assessing the risk of fetal chromosome abnormalities in pregnant women with ART.
