无创产前筛查时代下有创产前诊断取样技术
Invasive prenatal diagnosis sampling technology in the era of non-invasive prenatal testing
随着无创产前筛查(non-invasive prenatal testing,NIPT)的广泛应用,有创产前诊断已从一线筛查策略转变为针对高风险人群的最终确诊手段。对于无创筛查结果高风险、胎儿超声结构异常及特定遗传病史等高危指征,有创产前诊断凭借其诊断的确定性,作为获取胎儿完整遗传信息的“金标准”,其地位无可替代。文章旨在系统梳理有创产前诊断取样技术的最新进展、比较其优势与局限,并探讨未来发展方向,以期为相关临床实践与科学研究提供参考依据。
With the widespread application of non-invasive prenatal testing (NIPT),invasive prenatal diagnosis has shifted from being a first-line screening strategy to a final diagnostic tool for high-risk populations. For high-risk indicators such as high-risk results of non-invasive screening,fetal structural abnormalities in ultrasonography and specific genetic history,invasive prenatal diagnosis,with its diagnostic certainty,serves as the "gold standard" for obtaining complete genetic information of the fetus,and its status is irreplaceable. This article aims to systematically review the latest advancements in sampling techniques for invasive prenatal diagnosis,compare their advantages and limitations,and explore future development directions,with the hope of providing a reference basis for relevant clinical practice and scientific research.
