目的:探讨荧光定量聚合酶链式反应(QF-PCR)在快速产前诊断中的临床应用价值。方法:应用QF-PCR技术对2018年5月7日至2019年5月7日于扬州市妇幼保健院产前诊断中心行产前诊断的1 190例产前羊水样本进行13、18、21、X及Y的非整倍体产前诊断并与核型分析结果对比。结果:1 190例羊水QF-PCR共诊断出33例各种染色体异常，包括21-三体20例；18-三体4例及性染色体异常9例。结论:作为常见的快速诊断方法，QF-PCR诊断结果快速、准确，但还不能完全代替传统的核型分析。“,”Objective:To assess the clinical value of quantitative fluorescent polymerase chain reaction(QF-PCR) in rapid prenatal diagnosis.Methods:From May 2018 to May 2019, 1 190 amniotic fluid samples were detected by QF-PCR to check out aneuploidies of 13, 18, 21, X and Y, then the results were compared with those of traditional karyotype analysis.Results:The 33 abnormities including 20 cases with trisomy 21, 4 cases with trisomy 18 and 9 abnormities of sex chromosomes were checked out in 1190 amniotic fluid samples by rapid diagnosis.Conclusion:As a common rapid diagnostic method, QF-PCR has advantages of rapid and accurate, but still cannot completely replace the conventional karyotype analysis.
