关于无创产前检测 (NIPT)

当婴儿在母亲的体内生长时, 少量的婴儿基因(DNA)会流入到母亲的血液中。无创产前检测能有效的采用那少量的基因检测出由额外或缺失的染色体材料引起的某些异常。

 

您可以在怀孕的第10周开始进行这项血液并能检测到影响胎儿发育的染色体异常症。

简单的血液检测以筛查会影响胎儿发育的异常染色体

最早可以在怀孕的第10周进行

准确度超过99%

可选择知道胎儿的性别

采用全基因组测序方法 （Whole Genome Sequencing）
全面覆盖所有染色体

经由国际认证的韩国实验室进行测试

^高风险患者可获得高达300美元的确认测试资助

    免责声明
    没有任何测试是完美的。 DNA测试结果不能为所有孕妇提供明确的遗传风险。游离基因不能取代CVS或羊膜穿刺术的产前诊断的准确性和精确度。患者若具有阳性测试结果或其他测试结果应转介到遗传专家作咨询，并进行入侵性产前诊断以确认测试结果。获得阴性结果不能确保怀孕的过程不受其他影响。没有发现的结果亦不表示完全呈阴性。虽然该测试的结果是高度准确的，亦有机会由于胎盘，母体或胎儿嵌合或其他原因的关系，未必所有的染色体异常都能被检测到。医疗机构有责任提供信息给患者。
