Genetic testing of products of conception (POC) has been proposed as a tool to be used in the evaluation of patients with recurrent pregnancy loss (RPL). Following a complete RPL evaluation, POC results may reveal an aneuploidy and provide an explanation for the miscarriage in more than 55% of cases. When the cytogenetic result of the pregnancy loss reveals a euploid pregnancy, management should be directed towards the identification of treatable abnormalities. Furthermore, the results of POC testing might better define a subgroup of patients with unexplained RPL who may benefit from expectant management versus preimplantation genetics (aneuploid unexplained RPL) or investigational therapy (euploid unexplained RPL).
对妊娠产物（POC）进行基因检测已被提议作为评估复发性妊娠丢失（RPL）患者的一种工具。在进行完整的 RPL 评估后，POC 结果可能会发现非整倍体，并为 55%以上的流产提供解释。当妊娠丢失的细胞遗传学结果显示为正常二倍体妊娠时，应针对可治疗的异常进行管理。此外，POC 检测结果可能更好地定义一组不明原因 RPL 患者，这些患者可能从期待治疗（非整倍体不明原因 RPL）或试验性治疗（整倍体不明原因 RPL）中受益。
