Application of QF-PCR in amniotic fluid rapid prenatal diagnosis / 中国基层医药

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.
