ABSTRACT
Methods:
A total of 1 152 amniotic fluid samples were collected from pregnant women who underwent prenatal diagnosis in the Nanjing Maternity and Child Health Care Hospital, Women′s Hospital School of Medicine Zhejiang University, West China Second University Hospital, Sichuan University/West China Women′s and Children′s Hospital, and Xiamen Maternal and Child Health Hospital from September 2014 to August 2016. These samples were examined with SD-HRM and karyotyping simultaneously. Clinical sensitivity and specificity of SD-HRM were calculated, and Kappa values were measured to evaluate the consistency of detection results of the two methods.Results:
A total of 161 cases of trisomy 21, 60 cases of trisomy 18, and 5 cases of trisomy 13 were detected by SD-HRM in 1 152 prenatal samples, sensitivity and specificity were both up to 100%, and Kappa values is equal to 1 which were consistent with the results of karyotype analysis.Conclusion:
SD-HRM is validated to be highly accurate for the prenatal diagnosis of common trisomies, which is promising in the clinical practice.
